If problems persist please review logs:

  • Start with the log file with the recent modification time and traverse from any event backwards to the root cause of the problem
  • $TRAF_HOME$MY_SQROOT/sql/local_hadoop/*/log: Hadoop, HBase, and Hive logs.
  • $MY$TRAF_SQROOTHOME/logs: Trafodion logs.
  • In Trafodion 2.1 TM has been improved to log all critical events into tm_<nid>.log
  • Look for TM core files in directory /proc/sys/kernel/core_pattern or in $TRAF_HOME/sql/scripts
  • Look at the stdout_<traf_component> files in $TRAF_HOME/sql/scripts
