[jira] [Updated] (ACCUMULO-813) clear block caches on IOException

["Keith Turner (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/ACCUMULO-813?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Keith Turner updated ACCUMULO-813:
----------------------------------

         Priority: Major  (was: Blocker)
    Fix Version/s:     (was: 1.5.0)
                   1.6.0

Confirmed w/ Eric this was caused by bad col vis.  Clearing the block caches on IOException is still a good idea.  I lowered the priority though since the reasons for opening this bug are mitigated in 1.5.

> A user generated a bulk import file with illegal data.  After re-generating the file, they thought they could just move the file into HDFS with the new name.  Unfortunately, the block cache remembered some of the data, which caused the data at the block boundaries to be corrupt.
> One possible solution is to clear the block cache when an IOException occurs on a read.
