Subject [jira] [Commented] (TIKA-2643) Tika call hangs when processes a pdf on Cloudera Hadoop
Date Wed, 16 May 2018 14:29:00 GMT

    [ https://issues.apache.org/jira/browse/TIKA-2643?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16477504#comment-16477504
] 

feng ye commented on TIKA-2643:
-------------------------------

logger.debug("in helper funciton... ");
String content = tika.parseToString(stream);
 logger.debug("return from Tika call");

The above is from my code. You can see the "in helper function..." in my log but not "return
from Tika call". 

Cannot tell which one of these reasons is the top suspect. Why 1) is a factor?

> 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.
