Rajkumar Singh commented on HIVE-22397:
---------------------------------------
agreed with all your explanation about the best practices but the same sequence
of operation should not pass/fail intermittently, they should be either
consistently fail or pass e.g.
{code:java}
Open session:
1) ADD JAR hdfs:///user/hive/customsdtable.jar;
2) describe customsdtable; // this will succeed.
Another session:
1) describe customsdtable;
2) ADD JAR hdfs:///user/hive/customsdtable.jar;
3) describe customsdtable; // this will fail.
{code}
> "describe table" statement for the table backed by custom storage handler
> fail with CNF
