Aleksandr Shulman commented on HBASE-10073:
-------------------------------------------
I think the problem runs a little deeper. If there are two versions of slf4j
(or any dependency for that matter) on the classpath, then something will be
affected by a resulting incompatibility. Because of changes in the ordering of
the classpath in 0.96, I had to make some changes to my own setup scripts. Both
configurations one could consider reasonable or representative of what a common
user would do.
Before my change, I reported this issue.
After the change, hbase zkcli works fine, but there is a similar error now when
starting master (much worse!). The revert you are suggesting may fix it though.
I'll test it.
Here's the master startup error:

> [Hadoop1]: hbase zkcli broken due to slf4j incompatibility
> ----------------------------------------------------------
>
> Key: HBASE-10073
> URL: https://issues.apache.org/jira/browse/HBASE-10073
> Project: HBase
> Issue Type: Bug
> Components: Zookeeper
> Affects Versions: 0.96.1
> Environment: Centos6, sun-jdk-64bit-1.7.0.25
> Reporter: Aleksandr Shulman
> Assignee: Andrew Purtell
> Fix For: 0.98.0, 0.96.1, 0.99.0
>
> Attachments: 10073-0.96.patch
>
>
> Observed behavior:
> In my automation, I have a call to hbase zkcli. That call recently broke with
> this checkin:
> https://github.com/apache/hbase/commit/5af0a60efed91ac2084f25f13edb21db0f510e7c
> The error that is reported is:
> {code}++ ./hbase zkcli
> 11:19:58 Warning: $HADOOP_HOME is deprecated.
> 11:19:58
> 11:20:00 Exception in thread "main" java.lang.IllegalAccessError: tried to
> access field org.slf4j.impl.StaticLoggerBinder.SINGLETON from class

> org.apache.hadoop.hbase.zookeeper.ZooKeeperMainServer.main(ZooKeeperMainServer.java:78)
> 11:20:00 Build step 'Execute shell' marked build as failure{code}
> That said, this checkin is perfectly valid as each component should be
> allowed to specify its own dependencies.
> The issue is a deeper one of dependency mismatches.
> Note: This issue only affects hadoop1, not hadoop2. It also appears in trunk,
> where there is a similar checkin, but since trunk is not required to work
> against hadoop1, this is not an issue for trunk.
