Subject [jira] [Updated] (HDFS-8479) Erasure coding: fix striping related logic in FSDirWriteFileOp to sync with HDFS-8421
Date Tue, 26 May 2015 20:59:20 GMT

     [ https://issues.apache.org/jira/browse/HDFS-8479?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Zhe Zhang updated HDFS-8479:
----------------------------
    Status: Patch Available  (was: Open)

The patch is actually simpler than I expected. Through all EC patches we have changed several
times the way to check whether a file is striped / erasure coded. This patch just applies
the latest version to {{FSDirWriteFileOp}}. It also fixes a test failure because {{ThreadLocalRandom.current().nextLong()}}
could generate negative block IDs (but the block info is contiguous).
