Zeppelin is unable to get renewed kerberos ticket automatically.
Kerboers config has ticket renewal after 24h. Zeppelin stops executing jdbc queries after 24h , even though kerberos ticket is valid(i've checked the same via klist on hbase node).
Queries does not work even after waiting for 1h and even after logout-login again. Error is like :
'Couldn't find kerberos ticket..consider 'kinit'.
but it works fine if i restart jdbc interpreter.
So, It seems there any internal cache or something like that which has metadata of kerberos ticket and is there any config(way) to change the same so that we don't need to restart the interprator.
More details :I am using phoenix queries and using ADM account and Zeppelin version is 0.7.0
