--------------------------------------
Summary: Reduce the DiskIoMgr thread parameters for filesystems
that are not being tested
Key: IMPALA-12727
URL: https://issues.apache.org/jira/browse/IMPALA-12727
Project: IMPALA
Issue Type: Improvement
Components: Infrastructure
Reporter: Joe McDonnell
DiskIoMgr is using a large number of threads, most of which are idle. This
makes minidumps/cores larger and slower to process. For developers, this can
slow down gdb attach and navigating through the threads.
For our test infrastructure / development, we can reduce the threads for
filesystems that are not the TARGET_FILESYSTEM. If we aren't testing ABFS, then
we don't need the full set of ABFS threads. In general, we can reduce almost
all of the non-TARGET_FILESYSTEM DiskIoMgr thread counts to 1.
We should have a way to turn it off, but it seems like this could be the
default mode.
