Vinayakumar B updated HDFS-3488: -------------------------------- Labels: (was: BB2015-05-TBR) > BlockPoolSliceScanner#getNewBlockScanTime does not handle numbers > 31 bits > properly > ------------------------------------------------------------------------------------ > > Key: HDFS-3488 > URL: https://issues.apache.org/jira/browse/HDFS-3488 > Project: Hadoop HDFS > Issue Type: Bug > Reporter: Colin Patrick McCabe > Assignee: Colin Patrick McCabe > Priority: Minor > Attachments: HDFS-3488.001.patch > > > This code does not handle the case where period > 2**31 properly: > {code} > long period = Math.min(scanPeriod, > Math.max(blockMap.size(),1) * 600 * 1000L); > int periodInt = Math.abs((int)period); > return System.currentTimeMillis() - scanPeriod + > DFSUtil.getRandom().nextInt(periodInt); > {code} > So, for example, if period = 0x100000000, we'll map that to 0, and so forth. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
