CDH 5.7, Hive and Kerberos : stop responding to queries after 30 minutes

[#1]

Hi all,

We recently deployed kerberos on a CDH 5.7.1 using AD's KDC.

We configured HDFS to use AD's groups (all CDH users are created in the AD and linked with their respective groups(hdfs-group, impala-group, hive-group ... )) and we configured Sentry for the authorizations.

After starting the cluster, everything works fine. But after 30 minutes, Hive and Impala don't respond to queries and after a restart it works again for another 30 minutes.

Does anyone faced this problem ?

Thank you !
