GENERIC_INTERNAL_ERROR: Value exceeds One example that usually happen, e.g. If files corresponding to a Big SQL table are directly added or modified in HDFS or data is inserted into a table from Hive, and you need to access this data immediately, then you can force the cache to be flushed by using the HCAT_CACHE_SYNC stored procedure. see I get errors when I try to read JSON data in Amazon Athena in the AWS For example, if you transfer data from one HDFS system to another, use MSCK REPAIR TABLE to make the Hive metastore aware of the partitions on the new HDFS. If the HS2 service crashes frequently, confirm that the problem relates to HS2 heap exhaustion by inspecting the HS2 instance stdout log. Auto hcat sync is the default in releases after 4.2. To use the Amazon Web Services Documentation, Javascript must be enabled. When creating a table using PARTITIONED BY clause, partitions are generated and registered in the Hive metastore. How can I This step could take a long time if the table has thousands of partitions. (UDF). This section provides guidance on problems you may encounter while installing, upgrading, or running Hive.
