FAQ
Hi,

I am still confused what libs we need for clients. I keep seeing Guava
and I am not sure where this is used. I tried some (given, simple)
examples and cannot see where it is required as they all run just
fine. See

https://github.com/larsgeorge/hbase-book/blob/master/pom.xml

So the list that works for me is:

[INFO] +- commons-logging:commons-logging:jar:1.1.1:compile
[INFO] +- log4j:log4j:jar:1.2.16:compile
[INFO] +- org.apache.hadoop:hadoop-core:jar:0.20-append-r1044525:compile
[INFO] +- org.apache.zookeeper:zookeeper:jar:3.3.2:compile
[INFO] \- org.apache.hbase:hbase:jar:0.91.0-SNAPSHOT:compile

everything else is excluded. Looks like Guava is only used in the
MapReduce helper functions, no? In that case Guava only needs adding
when writing MR jobs? Is there a rule we could formulate?

    Hi,

    maybe the right thing would be to solve HBASE-2170[1] instead?

    [1] hbase lightweight client library as a distribution
    http://issues.apache.org/jira/browse/HBASE-2170

    Hi Thomas,

    Yeah, but that is a difficult topic no one is going to touch even with
    a 10-foot pole.

    Guava is not needed since
    https://issues.apache.org/jira/browse/HBASE-3264 (Patch removes it
    from a few places including MR support util).
    Your list looks right Lars,
