> NPE in DFSStripedInputStream.readWithStrategy
> ----------------------------------------------
>
> Key: HDFS-17893
> URL: https://issues.apache.org/jira/browse/HDFS-17893
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: ec
> Affects Versions: 3.5.0
> Reporter: Dave Marion
> Priority: Major
> Labels: pull-request-available
>
> [DFSStripedInputStream.readWithStrategy|https://github.com/apache/hadoop/blob/trunk/hadoop-hdfs-project/hadoop-hdfs-client/src/main/java/org/apache/hadoop/hdfs/DFSStripedInputStream.java#L391]
> checks to see if it is closed, then enters a retry loop where it ends up
> calling *readOneStripe* (line 421). *readOneStripe* calls *readStripe* on the
> {*}StatefulStripeReader{*}, which defaults to its parent class
> {*}StripeReader{*}. *StripeReader.readStripe* (line 356) on an exception
> calls close on the *DFSStripedInputStream* which ends up setting *decoder* to
> null.
> *DFSStripedInputStream.readWithStrategy* catches the IOException and retries
> calling *readOneStripe* again, which throws a NullPointerException in the
> call to *resetCurStripeBuffer* because the *decoder* is null when
> *useDirectBuffer* is called.
>
> With the retries that DFSStripedInputStream is doing in readWithStrategy,
> it's likely that either the StripedReader should not be closing the
> DFSStripedInputStream, or the closed check needs to happen again at the top
> of the retry loop.
