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

Manage Hadoop Environment

...

If you are doing Trafodion development on a pre-existing Hadoop distribution, then do the following:

  • Distribution: Use the distribution management too. For example: Apache Ambari or Cloudera Manager.
  • Regular Hadoop: Use the start/stop script for each Hadoop environment.

Local Hadoop

Use the following commands to manage the Hadoop environment.

CommandUsage
swstartallStart the complete Hadoop environment.
swstopallStops the complete Hadoop environment.
swstatusChecks the status of the Hadoop environment.
swuninstall_local_hadoopRemoves the Hadoop installation.

Downloading New Source Code

You need to do the following each time you download new source code.

Code Block
languagebash
cd <Trafodion source directory>
source ./env.sh
cd $MY_SQROOT/etc

# delete ms.env, if it exists
rm ms.env
cd $MY_SQROOT/sql/scripts
sqgen
Code Block
languagebash
titleExample: Refresh when Installing New Source Code
cd mysource/incubator-trafidion
source ./env.sh
cd $MY_SQROOT/etc

# delete ms.env, if it exists
