Ken Krugler commented on TIKA-2643:
-----------------------------------
When you've got conflicting jars on the classpath, you often run into this, as
the ordering of jars isn't guaranteed. So it can actually run fine one time,
and fail another time, due to some subtle perturbation of the environment.
> Tika call hangs when processes a pdf on Cloudera Hadoop

> Key: TIKA-2643
> URL: https://issues.apache.org/jira/browse/TIKA-2643
> Project: Tika
> Issue Type: Bug
> Components: parser
> Affects Versions: 1.17
> Environment: Cloudera Hadoop 5.8
> Reporter: feng ye
> Priority: Blocker
> Attachments: hang-stdout.txt, hang.zip, hs_err_pid32104.log,
> testJournalParser.pdf
>
>
> Tika.parseToString(InputStream) hangs when called within a MapReduce job to
> process a pdf file from Cloudera Hadoop 5.8 (observed on 5.4 too). It can
> process some other pdf files on the same cluster. I am attaching the file and
> the syslog as well as stdout logs. Interesting that the same file can be
> processed fine over a Hortonworks cluster.
> This issue is a blocker for us to make our feature based on Tika available to
> Cloudera cluster, a major flavor of Hadoop, so your timely attention would be
> very much appreciated.
