Hi, Did you set hdfs-site.xml in HADOOP_CONF_DIR? Your log says datanode exists at localhost. 16/03/23 15:21:46 INFO DFSClient: Excluding datanode 127.0.0.1:50010 CDH 5.5' hadoop roughly corresponds to hadoop 2.6, so building spark with hadoop 2.6 option might be good. http://www.cloudera.com/documentation/enterprise/5-5-x/topics/cdh_vd_cdh_package_tarball.html

HI, What did zkfc log say? I think zkfc manages namenode state.

Referring HDFS-5153, I took workaround. https://issues.apache.org/jira/browse/HDFS-5153 One of the couses is that I set dfs.datanode.data.dir to only one directory. So, I increased by several storages and rebalanced data manually. And then, I could boot hdfs with no currupt. However, if this is unexpected, I hope the block report function to be fixed. And another better solution is welcome.

Hi, Thank you for releasing CDH 5.5.0. This time, I upgraded our hadoop cluster to CDH 5.5.0 from CDH 5.4.8, and HDFS got CORRUPTED. In datanode log, datanode seemed to fail to send a block report by protobuf size limitation like below. In CDH 5.5.0, BlockListAsLongs was changed largely and this seems to be cause. Accoding to "Install and Upgrade Known Issues", ipc.maximum.data.length is 134217728 because I've encountered maximum configured RPC length error. Can I solve this problem without hacking protobuf jar?
