support webhdfs for feed replication
Hi,
I am new this group and wanted to check with the dev if webhdfs is
something the current trunk supports for feed replication. I have tried
to setup a cluster with webhdfs, however, oozie seems to fail to initialize
cluster with the following exception.

Re: support webhdfs for feed replication
Posted by Seetharam Venkatesh <ve...@innerzeal.com>.
I think Oozie needs to be configured with the schemes that you are
interested in.
oozie.service.HadoopAccessorService.supported.filesystems must have
webhdfs. I'll also check in a day to test this scenario.

Re: support webhdfs for feed replication
Posted by Praveen <sa...@gmail.com>.
Thanks for the response. Scheduling directly in oozie seems to work fine.
Also, using hdfs for target works fine as well. Am thinking if the error
stack is misleading.

@praveen , can u try directly scheduling in oozie ? other ppl have also
faced similar issue
http://grokbase.com/t/cloudera/cdh-user/1334qxqcyk/error-when-running-oozie-mapreduce-example
as Srikanth mentioned , webhdfs is supported by falcon.

RE: support webhdfs for feed replication
Posted by Srikanth Sundarrajan <sr...@hotmail.com>.
Seems like an issue with connection to JT from the oozie server. As such webhdfs is supported via falcon for replication.
