RegionTooBusyException Is Reported When Data Is Imported to a CloudTable HBase Table Through a Datasource Table
Symptom
A datasource table was used to import data to a CloudTable HBase table. This HBase table contains a column family and a rowkey for 100 million simulating data records. The data volume is 9.76 GB. The job failed after 10 million data records were imported.
Cause Analysis
- View driver error logs.
- View executor error logs.
- View task error logs.
The rowkey was poorly designed causing a large amount of traffic redirected to single or very few numbers of nodes.
Procedure
- Pre-partition the HBase.
- Hash the rowkey.
Summary and Suggestions
Distribute data to different RegionServer. Add distribute by rand() to the end of the insert statement.
