So I went and checked on the run times of Cloudera's internal integration test jenkins runs, and I noticed that recently the IntegrationTestBigLinkedList runs started running much slower.
With the slow monkey: 5 hr 58 min -> 11 hr With the calm monkey: 4 hr 36 min -> 6 hr 24 min IntegrationTestBulkLoad also has a slow down but it's much less dramatic 22 min -> 26 min This slow down doesn't seem to manifest itself with TestLoadAndVerify at all. But it has been pretty consistent since the build containing the following commits: Changes HBASE-9949 Fix the race condition between Compaction and StoreScanner.init HBASE-9949 Addendum removes readpoint parameter for getScanner() HBASE-9949 Revert due to TestHRegion failure HBASE-9869 Optimize HConnectionManager#getCachedLocation HBASE-9983 Lower the memory footprint of HRegionLocation HBASE-9869 Optimize HConnectionManager#getCachedLocation - remove SoftValueSortedMap To me the first three commits look like they cancel each so that leaves the last three commits as the most likely culprits. Does anyone have a thought on whey these would be causing problems with ITBLL ?
