> When I try running hbase using the code *./start-hbase.sh* , the terminal doesn't show an error or failure but logs do show it. Here I am dropping the link to the entire log file [log file|[http://justpaste.it/aqyjh|https://justpaste.it/aqyjh]] . I have tried some forums and reading documentation but nothing helped. Hadoop is compatible with Hbase version asHbase created a folder in Hadoop named */hbase* in the root directory of Hadoop and the directory does contain couple of directories (.hbck, .tmp, MasterData, WALs, archive, etc) and 2 files (hbase.id, hbase.version). So I don't think compatibility between Hadoop and Hbase is the issue here. Everything is running locally, literally everything as I am just testing some stuff. Also when I try doing *bin/hbase shell* , then the shell starts but anything I do in the shell for example if I type {*}status{*}, in the shell, I get the error which is same if I type any other code as "Error: KeeperErrorCode = ConnectionLoss for /hbase/master". I have uploaded two files of hbase which are the only two files I have altered to from the pre-built version of Apache. If you need any more information, please let me know.
