Liangjun He updated HBASE-28904:
--------------------------------
Description:
The Bulkload process consists of two steps:
1. generate hfiles using MR/SPARK and write them to an HDFS cluster.
2. execute 'hbase completebulkload [OPTIONS]
</PATH/TO/HFILEOUTPUTFORMAT-OUTPUT> <TABLENAME> ' or invoke the
BulkLoadHFilesTool API.
[HBASE-1721|https://issues.apache.org/jira/browse/HBASE-15172] implements
tiered storage capabilities for bulkload, but it is only applicable to
scenarios where hfiles generated by MR/SPARK are directly written to the HDFS
cluster used by HBase (tiered storage is configured). However, in most bulkload
scenarios, hfiles generated by MR/SPARK are first written to an offline HDFS
cluster (non-HBase HDFS Cluster, and tiered storage is not configured).
Subsequently, the 'hbase completebulkload' command is used to copy these hfiles
from the offline HDFS cluster to the HDFS cluster used by HBase, and rename
them to the appropriate table/partition/columnfamily directory. This scenario
is not supported by
[HBASE-1721|https://issues.apache.org/jira/browse/HBASE-15172], this issue will
support tiered storage for this more general bulkload scenario.
was:In the current HBase bulkload scenario, if a tiered storage policy is set
for the column family of a table and the operation involves different HDFS
clusters, the storage policy for the data imported via bulkload will not take
effect. We hope to enable the automatic activation of tiered storage policy in
the data copying scenario of bulkload.
