[jira] [Commented] (MAPREDUCE-6083) Map/Reduce dangerously adds Guava @Beta class to CryptoUtils

    [ https://issues.apache.org/jira/browse/MAPREDUCE-6083?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14198360#comment-14198360 ] 

Arun C Murthy commented on MAPREDUCE-6083:
------------------------------------------

[~ctubbsii] - Apologies for the late response. Unfortunately, we can't change guava versions in 2.6 since it would be incompatible.

> In recent 2.6.0-SNAPSHOTs, the use of LimitInputStream was added to CryptoUtils. This is part of the API components of Hadoop, which severely impacts users who were utilizing newer versions of Guava, where the @Beta and @Deprecated class, LimitInputStream, has been removed (removed in version 15 and later), beyond the impact already experienced in 2.4.0 as identified in HDFS-7040.
