Subject 0.13.0 Hive Issue - Hive client connecting via thrift
Date Wed, 12 Feb 2014 14:33:55 GMT
Hello.

We are running Hadoop 2.2.0, Hive 0.12.0.  We're seeing an error reading
integer fields from ORC tables that looks very similar to HIVE-5991.  In an
attempt to fix the issue, I downloaded Hive 0.13.0 trunk and compiled it.
 On starting Hive 0.13.0, I see the following messages:

2014-02-12 14:08:18,077 INFO  service.HiveServer

These messages continue to repeat until we're met with a 'Too many open
files' error after several thousand connections are made & files are
opened.

The thrift configuration worked with the older (0.12.0) Hive installation.
 Here is the output of my hive-site.xml:

  <configuration>

<!-- Hive Configuration can either be stored in this file or in the hadoop
configuration files  -->
<!-- that are implied by Hadoop setup variables.
                     -->
<!-- Aside from Hadoop setup variables - this file is provided as a
convenience so that Hive    -->
<!-- users do not have to edit hadoop configuration files (that may be
managed as a centralized -->
<!-- resource).
                    -->


<property>

  <!-- note: variable substituion not working here because it's loaded by
jdo, not Hive -->

</property>

<property>
  <name>hive.metastore.execute.setugi</name>
  <value>true</value>
</property>
</configuration>

Any ideas as to why the client is continually connecting & never closing
open sockets?
