Subject [jira] [Commented] (HIVE-12758) Parallel compilation: Operator::resetId() is not thread-safe
Date Wed, 06 Jan 2016 06:35:39 GMT

    [ https://issues.apache.org/jira/browse/HIVE-12758?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15085055#comment-15085055
] 

Gopal V commented on HIVE-12758:
--------------------------------

maybe mostly with a dumb awk script?

{code}
#!/usr/bin/awk -f
/Kryo ctor; don't use/ { change=1; print; next;}
/public / { if (change == 1) { sub(/public /,"private ");} }
/./ { change = 0; print; }
{code}
