Subject [jira] [Commented] (HIVE-11710) Beeline embedded mode doesn't output query progress after setting any session property
Date Wed, 23 Sep 2015 17:40:04 GMT

    [ https://issues.apache.org/jira/browse/HIVE-11710?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14904882#comment-14904882

Xuefu Zhang commented on HIVE-11710:
------------------------------------

[~aihuaxu], looking at the two patches, I seem to see that either patch has a possibility
of leaking resources, even if we consider in a single thread. The possible leaks are:

1. If new new FileOutputStream() is successful but new PrintStream() is not, then the FileOutputStream
instance is never closed.
2. In SQLOperation class, we never close these streams.

I think the only change we need to make in HiveCommandOperation is to fix #1. The original
tearDownSessionIO() seems fine with the changes in SQLOperation.

> Connect to beeline embedded mode {{beeline -u jdbc:hive2://}}. Then set anything in the
session like {{set aa=true;}}.
> After that, any query like {{select count(*) from src;}} will only output result but
no query progress.
