Joep Rottinghuis updated MAPREDUCE-3039:
----------------------------------------
Attachment: MAPREDUCE-3039-branch-0.22.patch
Will need somebody else with Avro experience to look at this please.
In the current patch I have not removed the wrapping of strings (CharSequence)
in JobSubmittedEvent. The same occurs in about 71 other places.
My concern is that when we insert a Utf8 wrapped string into a map, that when
other places try to do a get with a string we'll fail to find the entry. String
or other CharSequence will not equal any o.a.avro.util.Utf8 defines equals:
if (!(o instanceof Utf8)) return false;
In short I think I need to rip out all the Utf8 wrapping going on. Right?
> Make mapreduce use same version of avro as HBase

>
> HBase depends on avro 1.5.3 whereas hadoop-common depends on 1.3.2.
> When building HBase on top of hadoop, this should be consistent.
> Moreover, this should be consistent between common, hdfs, and mapreduce.
> Contribs seem to have declared a dependency on avro but are not in fact
> depending on it.
