This release fixes two issues that cause an exception that looks something like this:
java.lang.ArrayIndexOutOfBoundsException: 0 at com.datastax.bdp.hadoop.cfs.CassandraFileSystem.mkdir . . .
Issue 1: Array Index Out-Of-Bounds if Hadoop UserGroupInformation (UGI) returns no groups for the user
Resolves the problem caused by directory and file creation when running Mahout.
Issue 2: Array Index Out-Of-Bounds if checking permissions even when dfs.permissions is set to false on all nodes
Resolves the problem of the dfs.permissions setting in core-site.xml being ignored under certain conditions. For example, when submitting a remote job from a user that does not exist on an Analytics node, dfs.permissions set to false did not turn off permission checking as expected. User/group information code continued to be returned, resulting in an exception.
