----------------------------------------
Summary: A random data generator tool leveraging bulk load.
Key: HBASE-27904
URL: https://issues.apache.org/jira/browse/HBASE-27904
Project: HBase
Issue Type: New Feature
Components: util
Reporter: Himanshu Gwalani
As of now, there is no data generator tool in HBase leveraging bulk load. Since
bulk load skips client writes path and if an tooling over HBase need huge amout
of data for load/performance testing, bulk load can be leveraged.
The tool will generate data as a two-step process:
1. Generate HFiles with random data (using custom Mapper and
[HFileOutputFormat2|https://github.com/apache/hbase/blob/master/hbase-mapreduce/src/main/java/org/apache/hadoop/hbase/mapreduce/HFileOutputFormat2.java])
2. Bulk load those HFiles to the respective regions of the table using
[LoadIncrementalFiles|https://hbase.apache.org/2.2/devapidocs/org/apache/hadoop/hbase/tool/LoadIncrementalHFiles.html]
