> Hi,
> I installed CDH with Sentry and in Impala everything works fine. We have security demands that umask 077 should be used, so I changed default 022 to 077.
> But Hive says "No databases found.". In /var/log/hive is following stacktrace:
> 2016-07-08 16:05:58,085 WARN  org.apache.sentry.binding.metastore.SentryMetaStoreFilterHook: [HiveServer2-Handler-Pool: Thread-54]: Error getting DB list

> I investigated this issue and in sourcecode I found following lines:
> if("077".equalsIgnoreCase(defaultUmask)) {
>       LOG.error("HiveServer2 required a default umask of 077");
>       throw new InvalidConfigurationException(CommonConfigurationKeys.FS_PERMISSIONS_UMASK_KEY +
>           " should be 077 in non-testing mode");
>     }
> I think, that one exclamation mark is missing:
> if (!"077".equalsIgnoreCase(defaultUmask)).....
> Thanks
