Not that it could be related but if possible setup a Mysql or similar serious datastore….that
Hive can connect to…

Its possibly not prudent spending time to analyze problems caused  by derby metastore and
with Mysql u can start doing some heavy duty stinging with Hive :-)

Subject: Describe extended shows number of rows as 0


Hi,

When  I run analyze table command and run describe extended command, it shows the number of
rows as 0.

Query: DESCRIBE EXTENDED lineitem1;

Result:

.......parameters:{numPartitions=0, numFiles=4, transient_lastDdlTime=1367502213, numRows=0,
totalSize=3184, rawDataSize=0},

My Settings:
      <property>
                <name>javax.jdo.option.ConnectionURL</name>
                <value>jdbc:derby:;databaseName=/home/TempStatsStore;create=true</value>
                <description>JDBC connect string for a JDBC metastore</description>
        </property>

How to resolve this?



Thanks,
Aishwarya
