Description
The documentation is out of date. Some code references are broken:
1. http://hadoop.apache.org/docs/current/api/org/apache/hadoop/fs/FSDataInputStream.html
"All Implemented Interfaces:
Closeable, DataInput, org.apache.hadoop.fs.ByteBufferReadable, org.apache.hadoop.fs.HasFileDescriptor, PositionedReadable, Seekable "
2.http://hadoop.apache.org/docs/current/api/org/apache/hadoop/mapreduce/Cluster.html
renewDelegationToken(org.apache.hadoop.security.token.Token<org.apache.hadoop.mapreduce.security.token.delegation.DelegationTokenIdentifier> token)
Deprecated. Use Token.renew(org.apache.hadoop.conf.Configuration) instead
3.http://hadoop.apache.org/docs/current/api/org/apache/hadoop/mapred/JobConf.html
"Use MRAsyncDiskService.moveAndDeleteAllVolumes instead. "
I cannot find the MRAsyncDiskService class in the documentation of 2.0.3.
4.http://hadoop.apache.org/docs/current/api/org/apache/hadoop/mapred/join/CompositeRecordReader.html
