Robert Dyer updated HBASE-8856: ------------------------------- Description: I am using DelimitedKeyPrefixRegionSplitPolicy on my table. When I attempted to split the table from the web interface, it gives the error below. I believe the problem is org.apache.hadoop.hbase.regionserver.DelimitedKeyPrefixRegionSplitPolicy.getSplitPoint:75 - the call from super.getSplitPoint() (line 71) returns null and this condition is not checked. ------- {code} HTTP ERROR 500 Problem accessing /table.jsp.
