Revert "HBASE-24579: Failed SASL authentication does not result in an exception on client side (#1921)" This reverts commit bd79c4065ccb13a5e217d844376b3e7b9489d2fe. When Kerberos authentication succeeds, on the server side, after receiving the final SASL token from the client, we simply wait for the client to continue by sending the connection header. After HBASE-24579, on the client side, an additional readStatus() was added, which mistakenly assumes that after negotiation has completed a status code will be sent. However when authentication has succeeded the server will not send one. As a result the client will hang and only throw an exception when the configured read timeout is reached, which is 20 seconds by default. We cannot unilaterally send the expected additional status code from the server side because older clients will not expect it. The first call will fail because the client finds unexpected bytes in the stream ahead of the call response. Fabricating a call response also does not seem a viable strategy for backwards compatibility. The HBASE-24579 change needs to be reconsidered given the difficult backwards compatibility challenges here.

Apache HBase [1] is an open-source, distributed, versioned, column-oriented store modeled after Google' Bigtable: A Distributed Storage System for Structured Data by Chang et al.[2] Just as Bigtable leverages the distributed data storage provided by the Google File System, HBase provides Bigtable-like capabilities on top of Apache Hadoop [3]. To get started using HBase, the full documentation for this release can be found under the doc/ directory that accompanies this README. Using a browser, open the docs/index.html to view the project home page (or browse to [1]). The hbase 'book' at http://hbase.apache.org/book.html has a 'quick start' section and is where you should being your exploration of the hbase project. The latest HBase can be downloaded from an Apache Mirror [4]. The source code can be found at [5] The HBase issue tracker is at [6] Apache HBase is made available under the Apache License, version 2.0 [7] The HBase mailing lists and archives are listed here [8]. The HBase distribution includes cryptographic software.
