Rakesh R created HDFS-7764: ------------------------------ Summary: DirectoryScanner should cancel the future tasks when #compileReport throws exception Key: HDFS-7764 URL: https://issues.apache.org/jira/browse/HDFS-7764 Project: Hadoop HDFS Issue Type: Bug Components: datanode Affects Versions: 2.7.0 Reporter: Rakesh R Assignee: Rakesh R
If there is an exception while preparing the ScanInfo for the blocks in the directory, DirectoryScanner is immediately throwing exception and coming out of the current scan cycle. It would be good if he can signal #cancel() to the other pending tasks . DirectoryScanner.java {code} for (Entry<Integer, Future<ScanInfoPerBlockPool>> report : compilersInProgress.entrySet()) { try { dirReports[report.getKey()] = report.getValue().get(); } catch (Exception ex) { LOG.error("Error compiling report", ex); // Propagate ex to DataBlockScanner to deal with throw new RuntimeException(ex); } {code} -- This message was sent by Atlassian JIRA (v6.3.4#6332)
