[jira] [Created] (HBASE-5534) HBase shell's return value is almost
always 0
HBase shell's return value is almost always 0
---------------------------------------------
Key: HBASE-5534
URL: https://issues.apache.org/jira/browse/HBASE-5534
Project: HBase
Issue Type: Improvement
Reporter: Alex Newman
Assignee: Alex Newman
So I was trying to write some simple scripts to verify client connections to HBase using the shell and I noticed that the HBase shell always returns 0 even when it can't connect to an HBase server. I'm not sure if this is the best option. What would be neat is if you had some capability to run commands like
hbase shell --command='disable table;\ndrop table;' and it would error out if any of the commands fail to succeed. echo "disable table" | hbase shell could continue to work as it does now.

Oren Held commented on HBASE-5534:
----------------------------------
There should be one and only behavior for the CLI: return code != 0 if any error had occurred. That's the convention with all CLI tools on all platforms.
(I believe that creating a special --command flag, as suggested in the description, is redundant and confusing)
Imho, this issue should be referred to as a bug.
