[jira] [Commented] (PIG-4443) Write inputsplits in Tez to disk if the size is huge and option to compress pig input splits

["Ángel Álvarez (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/PIG-4443?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14595756#comment-14595756 ] 

Ángel Álvarez commented on PIG-4443:
------------------------------------

I have a script in PIG that loads data from Hive using org.apache.hive.hcatalog.pig.HCatLoader. This script works fine in Pig 0.14, but in Pig 0.15 I'm getting this error:

Requested data length 160452289 is longer than maximum configured RPC length 67108864

In Pig 0.14 I had to deal with this issue too, but I could always make it work by reducing the number of splits in the Hive tables created by Sqoop (using no more than 60 splits). Is there any special configuration needed?
