Nick Dimiduk created HBASE-25149: ------------------------------------ Summary: Profiling servlet stuck in a loop when output directory does not exist Key: HBASE-25149 URL: https://issues.apache.org/jira/browse/HBASE-25149 Project: HBase Issue Type: Bug Components: Performance Affects Versions: 2.3.0 Reporter: Nick Dimiduk
When the profiling servlet runs async-profiler when the output path ({{/tmp/prof-output}} doesn't exist or isn't writable by the {{hbase}} process, it will sit in a refresh loop indefinitely. The servlet should check that the output path is writable, or even make an attempt to create the output directory, and inform the user of the situation, rather than attempting and silently failing to generate the flame graph. -- This message was sent by Atlassian Jira (v8.3.4#803005)
