Request counters may become negative for heavily loaded regions ---------------------------------------------------------------
Key: HBASE-5283 URL: https://issues.apache.org/jira/browse/HBASE-5283 Project: HBase Issue Type: Bug Reporter: Zhihong Yu Requests counter showing negative count, example under 'Requests' column: -645470239 {code} Name Region Server Start Key End Key Requests usertable,user2037516127892189021,1326756873774.16833e4566d1daef109b8fdcd1f4b5a6. xxx.com:60030 user2037516127892189021 user2296868939942738705 -645470239 {code} RegionLoad.readRequestsCount and RegionLoad.writeRequestsCount are of int type. Our Ops has been running lots of heavy load operation. RegionLoad.getRequestsCount() overflows int.MAX_VALUE. It is set to D986E7E1. In table.jsp, RegionLoad.getRequestsCount() is assigned to long type. D986E7E1 is converted to long FFFFFFFFD986E7E1 which is -645470239 in decimal. Suggested fix is to make readRequestsCount and writeRequestsCount long type. -- This message is automatically generated by JIRA.
