Andy Isaacson created HDFS-3913: ----------------------------------- Summary: Refactor DataBlockScanner and clean up tests Key: HDFS-3913 URL: https://issues.apache.org/jira/browse/HDFS-3913 Project: Hadoop HDFS Issue Type: Bug Affects Versions: 2.0.1-alpha Reporter: Andy Isaacson Priority: Minor
In HDFS-3828 Eli observed bq. In getTotalScans rather than throw IOE if given a bpid w/o a scanner I believe this should be an assert (we should always have a scanner for a block pool if we've enbabled scanning, which we have if we're in DataBlockScanner) and Andy suggested bq. we could propagate a "please wake me up at time T" up from BlockPoolSliceScanner to DataBlockScanner#run and adjust the sleep time there, accordingly. If all threadpools continue to have work to do, then preserve the existing 5-second sleep; if all threadpools are done working then DataBlockScanner could go to sleep for much longer. -- This message is automatically generated by JIRA.
