[jira] [Created] (HBASE-19968) MapReduce test fails with NoClassDefFoundError against hadoop3

Ted Yu created HBASE-19968:
------------------------------

             Summary: MapReduce test fails with NoClassDefFoundError against hadoop3
                 Key: HBASE-19968
                 URL: https://issues.apache.org/jira/browse/HBASE-19968
             Project: HBase
          Issue Type: Bug
            Reporter: Ted Yu
            Assignee: Ted Yu


When running mapreduce tests against hadoop3, I observed the following:
{code}
[ERROR] testWithMockedMapReduceSingleRegion(org.apache.hadoop.hbase.mapred.TestTableSnapshotInputFormat)  Time elapsed: 0.024 s  <<< ERROR!
java.lang.NoClassDefFoundError: org/apache/hadoop/hdfs/server/blockmanagement/BlockInfo
  at org.apache.hadoop.hbase.mapred.TestTableSnapshotInputFormat.testWithMockedMapReduce(TestTableSnapshotInputFormat.java:178)
Caused by: java.lang.ClassNotFoundException: org.apache.hadoop.hdfs.server.blockmanagement.BlockInfo
  at org.apache.hadoop.hbase.mapred.TestTableSnapshotInputFormat.testWithMockedMapReduce(TestTableSnapshotInputFormat.java:178)
{code}
This was due to lack of dependency on hadoop-hdfs module in the hadoop-3.0 profile of hbase-mapreduce/pom.xml
