IMPALA-5240: Allow config of number of disk I/O threads per disk type Currently Impala defaults to 8 threads per flash disk and 1 thread per rotational disk. This can be overridden with --num_threads_per_disk, but that sets the thread count independent of disk type. This would allow control of the number of disk I/O threads spawned independently for solid state disks using "--num_io_threads_per_solid_state_disk" and for rotational disks using "--num_io_threads_per_rotational_disk" as startup parameters. Testing: Added backend tests that verify if "num_threads_per_disk", "num_io_threads_per_solid_state_disk" and "num_io_threads_per_rotational_disk" are used to spawn threads appropriately Change-Id: I094aff3747104104fe0465d73dcdbef5d9892f7c --- M be/src/runtime/disk-io-mgr-stress-test.cc M be/src/runtime/disk-io-mgr-stress.cc M be/src/runtime/disk-io-mgr-test.cc M be/src/runtime/disk-io-mgr.cc M be/src/runtime/disk-io-mgr.h M be/src/util/thread.cc M be/src/util/thread.h M fe/src/test/java/org/apache/impala/testutil/SentryServicePinger.java 8 files changed, 393 insertions(+), 341 deletions(-) git pull ssh://gerrit.cloudera.org:29418/Impala-ASF refs/changes/32/7232/4 -- To view, visit http://gerrit.cloudera.org:8080/7232 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-MessageType: newpatchset Gerrit-Change-Id: I094aff3747104104fe0465d73dcdbef5d9892f7c Gerrit-PatchSet: 4 Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-Owner: Bikramjeet Vig <bikramjeet....@cloudera.com> Gerrit-Reviewer: Bikramjeet Vig <bikramjeet....@cloudera.com> Gerrit-Reviewer: Matthew Jacobs <m...@cloudera.com> Gerrit-Reviewer: Tim Armstrong <tarmstr...@cloudera.com>
