[jira] [Commented] (HBASE-18415) Fix client.TestClientScannerRPCTimeout

["Chia-Ping Tsai (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HBASE-18415?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16096649#comment-16096649 ] 

Chia-Ping Tsai commented on HBASE-18415:
----------------------------------------

If the first call(CreateTableProcedure) succeed, the second call will receive the response from master with TableExistsException. That is weird for user because the table doesn't exist indeed before user submits the request. The "retry" should not break the behavior.
This issue exists in master, branch-2 and branch-1. We can reproduce this bug by reducing the timeout for RPC.
Ping [~stack] What to you think about this?
