Christopher Tubbs updated ACCUMULO-4021: ---------------------------------------- Fix Version/s: 1.8.0 1.7.1 1.6.5 > bulk imports slow file garbage collection > ----------------------------------------- > > Key: ACCUMULO-4021 > URL: https://issues.apache.org/jira/browse/ACCUMULO-4021 > Project: Accumulo > Issue Type: Bug > Components: gc > Affects Versions: 1.6.3 > Environment: large production system > Reporter: Eric Newton > Assignee: Eric Newton > Fix For: 1.6.5, 1.7.1, 1.8.0 > > > On a large system, bulk imports slow file garbage collection to a crawl. The > total number of files to be deleted was about 14 million. Initially, it would > run quickly, but then slow down, to the point where only a few files would be > deleted every few minutes. The jvm was only using 50% of the CPU (and > therefore, probably not GC thrashing). JStacks showed the collector scanning > the metadata table to remove referenced files from the delete list. > If the bulk ingest requests were stopped, the GC completed quickly. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
