Description
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
` INFO [Thread-10] com.linkedin.drelephant.analysis.HDFSContext : HDFS BLock size: 268435456`
and sometimes it is
` INFO [Thread-10] com.linkedin.drelephant.ElephantRunner : Backfill is not enabled`
Please advise how to address this issue.
Thanks.

Research direction
Start by reproducing startup while watching /logs/elephant/dr_elephant.log, focusing on the HDFSContext and ElephantRunner entries named in the report. Trace the startup path around those entries to determine why the process exits without an exception; done means the crash is reproducible, its cause is surfaced, and startup completes reliably.
