Hi Guys, Thanks for the reply. After analyzing Hiveserver logs we found that Hiveserver was unable to create new threads and hence Hive queries are not working. This is an intermittent issue. Whenever thread limit reached, Hiveserver is not able to create a new connection and stops responding. After restarting Hiveserver, it releases all threads and hive starts responding again. Here is the stack trace: at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) at java.lang.Thread.run(Thread.java:748) Caused by: java.io.IOException: Couldn't set up IO streams at org.apache.hadoop.ipc.Client$Connection.setupIOstreams(Client.java:791) at org.apache.hadoop.ipc.Client$Connection.access$2800(Client.java:373) at org.apache.hadoop.ipc.Client.getConnection(Client.java:1493) at org.apache.hadoop.ipc.Client.call(Client.java:1397) ... 73 more Caused by: java.lang.OutOfMemoryError: unable to create new native thread at java.lang.Thread.start0(Native Method) at java.lang.Thread.start(Thread.java:717) at org.apache.hadoop.ipc.Client$Connection.setupIOstreams(Client.java:784) ... 76 more We found the similar issue at Hortonworks community: https://community.hortonworks.com/content/supportkb/151804/error-javalangoutofmemoryerror-unable-to-create-ne.html According to Hortonworks, its a bug in HDP-2.3.4 version and it got resolved in a newer version of HDP. ...
