Hello, I used hbase Rowcounter on yarn , but the num of mappers was 1, and the progress was 0%. The input data was quit large, about 587GB. So how can I set the num of mappers when I use hbase RowCounter on yarn to make it faster? The commands I used were below: hadoop jar hbase-server-0.99.0-hadoop2-hadoop.jar importtsv -Dimporttsv.columns=HBASE_ROW_KEY,cf:c1,cf:c2,cf:c3,cf:c4,cf:c5,cf:c6,cf:c7 -Dimporttsv.separator="," -Dimporttsv.bulk.output=/inspur/output1 test /inspur/input/data/test.txt
hadoop jar hbase-server-0.99.0-hadoop2-hadoop.jar completebulkload /inspur/output1 test hbase org.apache.hadoop.hbase.mapreduce.RowCounter test ----------------- 刘璧怡 系统软件部研发三处 浪潮（北京）电子信息产业有限公司 TEL：010-61643876/18500682190
