For example in classes like ScriptOperator, FetchOperator, PartitionPruner etc, {noformat} LG.info("Executing " + Arrays.asList(wrappedCmdArgs)); LOG.info("tablename="+ hconf.get(HiveConf.ConfVars.HIVETABLENAME.varname)); {noformat} The two lines which are being logged separately can be clubbed using string builder and logged at once like {noformat} StringBuilder sb = new StringBuilder("Executing "); sb.append(Arrays.asList(wrappedCmdArgs)); sb.append("\ntablename="); sb.append(hconf.get(HiveConf.ConfVars.HIVETABLENAME.varname)); LOG.info(sb.toString()); {noformat} -- This message is automatically generated by JIRA.
