https://community.cloudera.com/t5/Support-Questions/Spark-Thrift-Server-Continually-Stops/m-p/120559#M83327 <P>I have a fresh install of Ambari (HDP 2.5 - version: 2.5.3.0-37) and I have a few services that will not remain running. There are not yet any users of this cluster; thus, it is simply a new cluster that is not yet in use.</P><P>One service that I am struggling to understand what may be going wrong is the Spark Thrift Server. </P><P>If I attempt to start the Spark Thrift Server, it generally stops within 1-5 minutes. Even upon a full reboot of the entire cluster this service will stop soon thereafter.</P><P>The only output I can find is:</P><PRE>[ambari-heartbeat-processor-0] HeartbeatProcessor:612 - State of service component SPARK_THRIFTSERVER of service SPARK of cluster hdpcluster has changed from STARTED to INSTALLED at host hdpcnode4 according to STATUS_COMMAND</PRE><P>Being this is a cluster, the Spark Thrift Server is running on node4 and ambari is on node1. The above log entry I find on node1 within /var/log/ambari-server/ambari-server.log. My guess is there may be more info about this failure in another log file but I have not had luck finding where this additional log data may be found.</P> Thu, 23 Feb 2017 03:28:02 GMT marc_fussell 2017-02-23T03:28:02Z
