Thanks,
I ended up just installing HBase 0.18 on Hadop 0.18.2.
However, I am getting the following errors when I run a map/reduce job
that inserts data into an HBase table:
java.lang.NoSuchMethodError:
org.apache.hadoop.hbase.io.BatchUpdate.put(Lorg/apache/hadoop/io/Text;[B)V
...
at org.apache.hadoop.mapred.MapRunner.run(MapRunner.java:47)
at org.apache.hadoop.mapred.MapTask.run(MapTask.java:227)
at
org.apache.hadoop.mapred.TaskTracker$Child.main(TaskTracker.java:2207)
Any ideas why I would be getting this?
I added the HBase jar file and hbase/conf directory the hadoop
classpath in hadoop-env.sh.
Thanks,
Ryan
