sequence files created by HBASE export utility aren't readable

问题

I tried the HBase export tool to transfer a table to HDFS. I tried to hadoop dfs -text the file to see a collection of contents. However, I got a fatal error:

java.lang.RuntimeException: java.io.IOException: WritableName can't load class: org.apache.hadoop.hbase.io.ImmutableBytesWritable

Do I need to integrate any configuration to include the class in my hadoop runtime?

A sequenceFile is a binary format. you can access it using Hadoop programing API or you can try a tool like forklift
