Subject [jira] [Commented] (HADOOP-11755) Update avro version to have PowerPC supported Snappy-java
Date Thu, 26 Mar 2015 10:50:53 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-11755?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14381693#comment-14381693

Steve Loughran commented on HADOOP-11755:

Linking to HADOOP-9991, the general "update JARs" JIRA.

Upgrading dependencies is one of the key backwards compatibility troublespots: we don't want
to ship old binaries, but we often have to for fear of breaking things downstream. 

There isn't going to be a rush to do this for Avro; it's not going to happen until after a
release has been made and everyone is happy avro and snappy releases are not going to break
things such as existing MR workloads.

You are of course free to install later versions of avro (even unreleased ones) in your own

>             Project: Hadoop Common
>          Issue Type: Task
>          Components: build
>    Affects Versions: 3.0.0
>         Environment: PowerPC64, PowerPC64LE
>            Reporter: Ayappan
> Hadoop downloads Snappy-java version (which don't have PowerPC native libraries)
through avro 1.7.4 dependency. 
> Current Avro development version ( 1.8.0-SNAPSHOT) has updated the snappy-java version
to which has ppc64 & ppc64le native libraries.So Hadoop needs to update the avro
version to the upcoming release ( probably 1.7.8) to have PowerPC supported snappy-java in
its lib.
