Description

Hadoop interface Closeable has been deprecated for quite some time to favor java.io.Closeable. Since we support only hadoop 1.0 and above now, we can replace the deprecated Closeable with the java one. We can also clean up some hack we did as well, for example, HBASE-10029.

Issue Links

• depends upon: HDFS-5566 HA namenode with QJM created from org.apache.hadoop.hdfs.server.namenode.ha.ConfiguredFailoverProxyProvider should implement Closeable
• relates to: HBASE-10029 Proxy created by HFileSystem#createReorderingProxy() should properly close when connecting to HA namenode
