> 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
