Method Details

extractAuthName

public static String extractAuthName(org.apache.zookeeper.data.ACL acl)

translateZooPerm

public static String translateZooPerm(int perm)

translate the ZooKeeper ACL perm bits into a string. The output order is cdrwa (when all perms are set) Copied from `org.apache.zookeeper.ZKUtil.getPermString()` added in more recent ZooKeeper versions.

checkWritableAuth

public static ZooAclUtil.ZkAccumuloAclStatus checkWritableAuth(List<org.apache.zookeeper.data.ACL> acls)

Process the ZooKeeper acls and return a structure that shows if the accumulo user has ALL (cdrwa) access and if any other user has anything other than read access.

• Accumulo having access is expected - anything else needs checked
• Anyone having more than read access is unexpected and should be checked.

Parameters:

acls - ZooKeeper ACLs for a node

Returns:

acl status with accumulo and other accesses.
