Description

When running mapreduce tests against hadoop3, I observed the following:

[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)

This was due to lack of dependency on hadoop-hdfs module in the hadoop-3.0 profile of hbase-mapreduce/pom.xml
