CloudFSMetrics

class CloudFSMetrics extends SparkPlugin

Monitor S3A I/0 metrics using Hadoop's API FileSystem.getGlobalStorageStatistics FileSystem.getGlobalStorageStatistics has been introduced in Hadoop (client) version 2.8

Note: use with Spark 3.x built with Hadoop 3.2 profile (or higher, when available) or use it with Spark built without Hadoop and use your own Hadoop client version 2.8 or higher. Limitation: this currently supports only one filesystem at a time

Parameters: filesystem name: --conf spark.cernSparkPlugin.cloudFsName=<name of the Hadoop compatible filesystem> (example: s3a) register metrics on the driver conditional to --conf spark.cernSparkPlugin.registerOnDriver=true
