dr-elephant crashes on startup

Open nutscrack opened this issue 6 years ago • 2 comments

Hi, When I start dr-elephant it crashes with no exception in the logs. Sometimes the last entry of the /logs/elephant/dr_elephant.log file is

<timestemp> INFO [Thread-10] com.linkedin.drelephant.analysis.HDFSContext : HDFS BLock size: 268435456

and sometimes it is

<timestemp> INFO [Thread-10] com.linkedin.drelephant.ElephantRunner : Backfill is not enabled

Please advise how to address this issue. Thanks.

Can you please look into exception log. In case of startup failure it would be available in dr.log or logs/application.log/

There is no exception in the log. dr.log file does not exist and logs/application.log says Application started (Prod) In addition, in /logs/elephant/dr_elephant.log file there is an entry stating Dr.elephant has started and then entries that I mentioned previously. However, 2 consecutive start commands executed 1 min one after another do succeed, which leads me to conclusion that dr-elephant crashes
