Subject [jira] [Updated] (HADOOP-11492) Bump up curator version to 2.7.1
Date Fri, 12 Feb 2016 17:41:18 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-11492?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Allen Wittenauer updated HADOOP-11492:
--------------------------------------
    Release Note: 
<!-- markdown -->
Apache Curator version change: Apache Hadoop has updated the version of Apache Curator used
from 2.6.0 to 2.7.1. This change should be binary and source compatible for the majority of
downstream users. Notable exceptions:

* Binary incompatible change: org.apache.curator.utils.PathUtils.validatePath(String) changed
return types. Downstream users of this method will need to recompile.
* Source incompatible change: org.apache.curator.framework.recipes.shared.SharedCountReader
added a method to its interface definition. Downstream users with custom implementations of
this interface can continue without binary compatibility problems but will need to modify
their source code to recompile.
* Source incompatible change: org.apache.curator.framework.recipes.shared.SharedValueReader
added a method to its interface definition. Downstream users with custom implementations of
this interface can continue without binary compatibility problems but will need to modify
their source code to recompile.

Downstream users are reminded that while the Hadoop community will attempt to avoid egregious
incompatible dependency changes, there is currently no policy around when Hadoop's exposed
dependencies will change across versions (ref http://hadoop.apache.org/docs/current/hadoop-project-dist/hadoop-common/Compatibility.html#Java_Classpath
).
