    https://issues.apache.org/jira/browse/AMBARI-4928


Repository: ambari


Description
-------

I couldnt launch the hive cli with the following exception being dumped
{code}
Exception in thread "main" java.lang.RuntimeException: org.apache.hadoop.security.AccessControlException:
Permission denied: user=hive, access=READ_EXECUTE, inode="/apps/hive/install":hive:hdfs:drw-r-xr-x
	at org.apache.hadoop.hdfs.server.namenode.FSPermissionChecker.checkFsPermission(FSPermissionChecker.java:265)
	at org.apache.hadoop.hdfs.server.namenode.FSPermissionChecker.check(FSPermissionChecker.java:251)

	at org.apache.hadoop.hdfs.server.namenode.FSNamesystem.checkPermission(FSNamesystem.java:5441)
{code}

There were no JARs under {{/apps/hive/install}}. 

These were the following hdfs permissions. Notable is {{/apps/hive/insatll}} permissions of
0655. 
{code}
$ hadoop fs -ls /apps
