[jira] [Created] (IMPALA-5909) File handle cache causes HDFS to log excessive errors when trying to unbuffer files

Tim Armstrong created IMPALA-5909:
-------------------------------------

             Summary: File handle cache causes HDFS to log excessive errors when trying to unbuffer files
                 Key: IMPALA-5909
                 URL: https://issues.apache.org/jira/browse/IMPALA-5909
             Project: IMPALA
          Issue Type: Bug
          Components: Backend
    Affects Versions: Impala 2.10.0
            Reporter: Tim Armstrong
            Assignee: Joe McDonnell


On a few different clusters I've seen a lot of errors like this in the logs:
{code}
org/apache/hadoop/fs/FSDataInputStream#unbuffer failed: error:
UnsupportedOperationException: this stream does not support unbuffering.java.lang.UnsupportedOperationException: this stream does not support unbuffering.
        at org.apache.hadoop.fs.FSDataInputStream.unbuffer(FSDataInputStream.java:233)
{code}

It doesn't seem harmful but adds a lot of noise to the logs for a non-error condition.
