Hi, I would like to know if it is feasbile to change the blocksize of Hadoop while map reduce jobs are executing? and if not would the following work? 1. stop map-reduce 2. stop-hbase 3. stop hadoop 4. change hadoop-sites.xml to reduce the blocksize 5. restart all whether the data in the hbase tables will be safe and automatically split after changing the block size of hadoop??
Thanks, Raakhi
