Could you follow below process 1)# sudo service postgresql start Starting postgresql service:[FAILED] If failed 2))Moved the data directory to [root@centos pgsql]# cd /var/lib/pgsql [root@centos pgsql]# mv -f data/ data_bkp [root@centos pgsql]# pwd /var/lib/pgsql 3) Check how your postgresql address how its listening $ grep listen /var/lib/pgsql/data/postgresql.conf if 'localhost' change to "*" 4) Start the postgresql database # sudo service postgresql start ( It should be ok) Then proceed with install ambari and setup the server. ...

Please find more information InputFormat describes the input-specification for a MapReduce job. The MapReduce framework relies on the InputFormat of the job to: Validate the input-specification of the job. Split-up the input file(s) into logical InputSplit instances, each of which is then assigned to an individual Mapper. Provide the RecordReader implementation used to glean input records from the logical InputSplit for processing by the Mapper. The default behavior of file-based InputFormat implementations, typically sub-classes of FileInputFormat, is to split the input into logical InputSplit instances based on the total size, in bytes, of the input files. However, the FileSystem blocksize of the input files is treated as an upper bound for input splits. A lower bound on the split size can be set via mapreduce.input.fileinputformat.split.minsize. Clearly, logical splits based on input-size is insufficient for many applications since record boundaries must be respected. In such cases, the application should implement a RecordReader, who is responsible for respecting record-boundaries and presents a record-oriented view of the logical InputSplit to the individual task. TextInputFormat is the default InputFormat. The Hadoop job client then submits the job (jar/executable etc.) and configuration to the ResourceManager which then assumes the responsibility of distributing the software/configuration to the slaves(HDFS or Datanodes), scheduling tasks and monitoring them, providing status and diagnostic information to the job-client. if this is help full coments and accept are appreciated. ...
