Is there a way to prevent regions from splitting while we are running a mapreduce job that does a lot of Puts? It seems that there is a lot of HDFS activity related to the splitting of regions while my M/R job is doing the puts. Is it sensible to disable splitting during the job that does lots of Put? Would there be any danger in this (i.e. disabling splitting during the job, and re-enabling it when the job completes)?
I see the hbase.regionserver.thread.splitcompactcheckfrequency could be used to make splits happen less frequently, but what I'd really like is for splitting to be disabled, then re-enabled later. -Geoff
