Charles PORROT updated HBASE-20748:
-----------------------------------
Description:
The _bulkLoad_ methods of _class org.apache.hadoop.hbase.spark.HBaseContext_
use the system's current time for the version of the cells to bulk-load.
This makes this method, and its twin _bulkLoadThinRows_, useless if you need to
use your own versionning system.
Thus, I propose a third _bulkLoad_ method, based on the original method.
Instead of using an _Iterator(KeyFamilyQualifier, Array[Byte])_ as the basis
for the writes, this new method would use an _Iterator(KeyFamilyQualifier,
Array[Byte], Long_), with the _Long_ being the version.
In case of illogical version (for instance, a negative version), the method
would throw back to the current timestamp.
See the attached file for a proposal of this new _bulkLoad_ method.
