Then I upgraded to hadoop2(Upgrade was successful).After up-gradation I am not able to read 100 blocks..Then I gone through code,while upgrading we are not considering blocks which are in BBW(only current folder we are hardlink to new current file).I think we need to handle BBW blocks also since hbase will sync files(below blocksize) without close which will be stored in BBW..This is like dataloss only..
