---------------------------------------
Summary: JvmPauseMonitor should dump the full Java stacktraces
Key: IMPALA-13434
URL: https://issues.apache.org/jira/browse/IMPALA-13434
Project: IMPALA
Issue Type: Bug
Components: Frontend
Reporter: Quanlong Huang
Assignee: Quanlong Huang
JvmPauseMonitor.checkForDeadlocks() will dump the stacktrace of threads.
However, it uses Thread.toString() which will only dump 8 frames at most.
Stacktrace deeper than that will be truncated, e.g.

We can use the same code we added for IMPALA-5392 to dump the full stacktrace.
