- Field Detail
  - GCS_CONFIG_PREFIX
```
public static final String GCS_CONFIG_PREFIX
```
    See Also:
    
    Constant Field Values
  - CONFIG_KEY_PREFIXES
```
public static final List<String> CONFIG_KEY_PREFIXES
```
  - GCS_ROOT_URL
```
public static final HadoopConfigurationProperty<String> GCS_ROOT_URL
```
    Configuration key for the Cloud Storage API endpoint root URL.
  - GCS_SERVICE_PATH
```
public static final HadoopConfigurationProperty<String> GCS_SERVICE_PATH
```
    Configuration key for the Cloud Storage API endpoint service path.
  - PERMISSIONS_TO_REPORT
```
public static final HadoopConfigurationProperty<String> PERMISSIONS_TO_REPORT
```
    Key for the permissions that we report a file or directory to have. Can either be octal or symbolic mode accepted by FsPermission(String)
    Default value for the permissions that we report a file or directory to have. Note: We do not really support file/dir permissions but we need to report some permission value when Hadoop calls getFileStatus(). A MapReduce job fails if we report permissions more relaxed than the value below and this is the default File System.
  - BLOCK_SIZE
```
public static final HadoopConfigurationProperty<Long> BLOCK_SIZE
```
    Configuration key for default block size of a file.
    Note that this is the size that is reported to Hadoop FS clients. It does not modify the actual block size of an underlying GCS object, because GCS JSON API does not allow modifying or querying the value. Modifying this value allows one to control how many mappers are used to process a given file.
  - GCS_HIERARCHICAL_NAMESPACE_ENABLE
```
public static final HadoopConfigurationProperty<Boolean> GCS_HIERARCHICAL_NAMESPACE_ENABLE
```
    Configuration key for enabling hierarchical namespace buckets.
    If this is enabled, rename folder operation on a Hierarchical namespace enabled bucket will be performed by calling the rename API.
  - DELEGATION_TOKEN_BINDING_CLASS
```
public static final HadoopConfigurationProperty<String> DELEGATION_TOKEN_BINDING_CLASS
```
    Configuration key for Delegation Token binding class. Default value: none
  - GCS_PROJECT_ID
```
public static final HadoopConfigurationProperty<String> GCS_PROJECT_ID
```
    Configuration key for GCS project ID. Default value: none
  - GCS_WORKING_DIRECTORY
```
public static final HadoopConfigurationProperty<String> GCS_WORKING_DIRECTORY
```
    Configuration key for initial working directory of a GHFS instance. Default value: '/'
  - GCE_BUCKET_DELETE_ENABLE
```
public static final HadoopConfigurationProperty<Boolean> GCE_BUCKET_DELETE_ENABLE
```
    If true, recursive delete on a path that refers to a GCS bucket itself ('/' for any bucket-rooted GoogleHadoopFileSystem) or delete on that path when it's empty will result in fully deleting the GCS bucket. If false, any operation that normally would have deleted the bucket will be ignored instead. Setting to 'false' preserves the typical behavior of "rm -rf /" which translates to deleting everything inside of root, but without clobbering the filesystem authority corresponding to that root path in the process.
  - GCS_REQUESTER_PAYS_MODE
```
public static final HadoopConfigurationProperty<RequesterPaysOptions.RequesterPaysMode> GCS_REQUESTER_PAYS_MODE
```
    Configuration key for GCS project ID. Default value: "DISABLED"
  - GCS_REQUESTER_PAYS_PROJECT_ID
```
public static final HadoopConfigurationProperty<String> GCS_REQUESTER_PAYS_PROJECT_ID
```
    Configuration key for GCS Requester Pays Project ID. Default value: none
  - GCS_REQUESTER_PAYS_BUCKETS
```
public static final HadoopConfigurationProperty<Collection<String>> GCS_REQUESTER_PAYS_BUCKETS
```
    Configuration key for GCS Requester Pays Buckets. Default value: none
  - GCS_FILE_CHECKSUM_TYPE
```
public static final HadoopConfigurationProperty<GoogleHadoopFileSystemBase.GcsFileChecksumType> GCS_FILE_CHECKSUM_TYPE
```
    Configuration key for which type of FileChecksum to return; if a particular file doesn't support the requested type, then getFileChecksum() will return null for that file.
  - GCS_PERFORMANCE_CACHE_ENABLE
```
public static final HadoopConfigurationProperty<Boolean> GCS_PERFORMANCE_CACHE_ENABLE
```
    Configuration key for using a local item cache to supplement GCS API "getFile" results. This provides faster access to recently queried data. Because the data is cached, modifications made outside of this instance may not be immediately reflected. The performance cache can be used in conjunction with other caching options.
  - GCS_PERFORMANCE_CACHE_MAX_ENTRY_AGE_MILLIS
```
public static final HadoopConfigurationProperty<Long> GCS_PERFORMANCE_CACHE_MAX_ENTRY_AGE_MILLIS
```
    Configuration key for maximum number of milliseconds a GoogleCloudStorageItemInfo will remain "valid" in the performance cache before it's invalidated.
  - GCS_STATUS_PARALLEL_ENABLE
```

```

  - GCS_COPY_WITH_REWRITE_ENABLE
```
public static final HadoopConfigurationProperty<Boolean> GCS_COPY_WITH_REWRITE_ENABLE

public static final HadoopConfigurationProperty<Integer> GCS_HTTP_MAX_RETRY
```
    Configuration key for the max number of retries for failed HTTP request to GCS. Note that the connector will retry *up to* the number of times as specified, using a default ExponentialBackOff strategy.
    Also, note that this number will only control the number of retries in the low level HTTP request implementation.
  - GCS_HTTP_CONNECT_TIMEOUT
```
public static final HadoopConfigurationProperty<Integer> GCS_HTTP_CONNECT_TIMEOUT
```
    Configuration key for the connect timeout (in millisecond) for HTTP request to GCS.

    BASIC: Stream is closest analogue to direct wrapper around low-level HTTP stream into GCS.

    FLUSHABLE_COMPOSITE: Stream behaves similarly to SYNCABLE_COMPOSITE, except hflush() is also supported. It will use the same implementation of hsync().
  - GCS_OUTPUT_STREAM_BUFFER_SIZE

  - GCS_INPUT_STREAM_FAST_FAIL_ON_NOT_FOUND_ENABLE
```
public static final HadoopConfigurationProperty<Boolean> GCS_INPUT_STREAM_FAST_FAIL_ON_NOT_FOUND_ENABLE
```
    If true, on opening a file we will proactively perform a metadata GET to check whether the object exists, even though the underlying channel will not open a data stream until read() is actually called. This is necessary to technically match the expected behavior of Hadoop filesystems, but incurs an extra latency overhead on open(). If the calling code can handle late failures on not-found errors, or has independently already ensured that a file exists before calling open(), then you can set this to false for more efficient reads.
    Note, this is known to not work with YARN CommonNodeLabelsManager and potentially other Hadoop components. That's why it's not recommended to set this property to false cluster-wide, instead set it for a specific job/application that is compatible with it.

```
    Tunes reading objects behavior to optimize HTTP GET requests for various use cases.
