Hi Devs
The region 9e28c97ccec104f3174ecf343cb59157 is a parent region. It got splitted into 2 daughter regions. The CatalogJanitor deleted this entry from META. Subsequent run of Catalog Janitor did not find the deleted region from META. After 5 times of CatalogJanitor running, it again found the deleted region. Anyway this time as the region was deleted from HDFS we got the below warn log. 2012-01-13 07:46:49,552 WARN org.apache.hadoop.hbase.regionserver.HRegion: Failed delete of hdfs://193.195.18.121:9000/hbase/Htable_UFDR_037/9e28c97ccec104f3174ecf343cb 59157 But why did the CatalogJanitor again pick up this deleted region in META. fullScan(). The same scenario has happened for about 6 regions in the same time. From the RS logs we could not find any operation pertaining to this region during that time. Any clues or suggestions? Regards Ram
