Subject [jira] [Created] (ACCUMULO-813) clear block caches on IOException
Date Mon, 15 Oct 2012 16:40:03 GMT
Eric Newton created ACCUMULO-813:

             Summary: clear block caches on IOException
                 Key: ACCUMULO-813
             Project: Accumulo
          Issue Type: Improvement
          Components: tserver
            Reporter: Eric Newton
            Assignee: Keith Turner
            Priority: Minor
             Fix For: 1.5.0

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.
