There is no data. For routine partition creation, MSCK command analysis:MSCK REPAIR TABLEThe command is mainly used to solve the problem that data written by HDFS DFS -PUT or HDFS API to the Hive partition table cannot be queried in Hive. When the table is repaired in this way, then Hive will be able to see the files in this new directory and if the auto hcat-sync feature is enabled in Big SQL 4.2 then Big SQL will be able to see this data as well. 2. . By limiting the number of partitions created, it prevents the Hive metastore from timing out or hitting an out of memory error. Dlink MySQL Table.
