Hi,
After upgrading from Hive 0.1.4 to Hive 1.2.1 I had to turn off concurrency in Hive to make it work by setting hive.support.concurrency to true in hive-site.xml. Now my Hive 0.1.4 supported concurrency and I use Oracle as my metastore.. To enable concurrency in Hive 0.1.4 I ran the script hive-txn-schema-0.14.0.oracle.sql. However, there is no new one for Hive 1.2.1 so I gather there is no change. Now the problem I am facing is when I turn on concurrency in Hive I get error ERROR [main]: curator.ConnectionState (ConnectionState.java:checkTimeouts(201)) - Connection timed out for connection string (hdw1.hadoop.local:2181,hdw2.hadoop.local:2181,hdw3.hadoop.local:2181) and timeout (15000) / elapsed (586102) WARN [main]: curator.ConnectionState (ConnectionState.java:checkTimeouts(192)) - Connection attempt unsuccessful after 608168 (greater than max timeout of 600000). Resetting connection and trying again with a new connection. INFO [main]: zookeeper.ZooKeeper (ZooKeeper.java:<init>(438)) - Initiating client connection, connectString=hdw1.hadoop.local:2181,hdw2.hadoop.local:2181,hdw3.hadoop.loca l:2181 sessionTimeout=600000 watcher=org.apache.curator.ConnectionState@8025ec7 And the query just hanges. I have zookeeper running. So I am not sure the cause. Have I missed something in upgrade. Without concurrency (i.e. hive.support.concurrency set to 'false) Hive works fine.
