Jing Zhao updated HDFS-7749:
----------------------------
Attachment: HDFS-7749.000.patch
Initial patch. The patch includes the following work:
# Use an INode feature ({{FileWithStripedBlocksFeature}}) to support striped
blocks in INodeFile
# Persist striped blocks to FSImage
# Add {{BlockInfoStripedUnderConstruction}} to present under-construction
striped blocks
# Add initial support for conversion between complete striped blocks and
under-construction striped blocks
# Disallow truncate, append, and concat on files with striped blocks. We can
support these operations for striped blocks in the future.
The current patch is more than 100KB. I will split it into smaller ones if
necessary.
