But that is slow because it sequentially lists > then renames files and directories, one-by-one. The latencies of list > and rename make things slow. > Google GCS lacks the atomic directory rename required for v1 correctness; > v2 can be used (which doesn't have the job commit performance limitations), > but it's not safe. > Proposed > * Add a new FileOutputFormat committer which uses an intermediate manifest to > pass the list of files created by a TA to the job committer. > * Job committer to parallelise reading these task manifests and submit all the > rename operations into a pool of worker threads. (also: mkdir, directory deletions on cleanup) > * Use the committer plugin mechanism added for s3a to make this the default committer for ABFS > (i.e. no need to make any changes to FileOutputCommitter) > * Add lots of IOStatistics instrumentation + logging of operations in the JobCommit > for visibility of where delays are occurring. > * Reuse the S3A committer _SUCCESS JSON structure to publish IOStats & other data > for testing/support. > This committer will be faster than the V1 algorithm because of the parallelisation, and > because a manifest written by create-and-rename will be exclusive to a single task > attempt, delivers the isolation which the v2 committer lacks. > This is not an attempt to do an iceberg/hudi/delta-lake style manifest-only format > for describing the contents of a table; the final output is still a directory tree > which must be scanned during query planning. > As such the format is still suboptimal for cloud storage -but at least we will have > faster job execution during the commit phases. > > Note: this will also work on HDFS, where again, it should be faster than > the v1 committer. However the target is very much Spark with ABFS and GCS; no plans to worry about MR as that simplifies the challenge of dealing with job restart (i.e. you don't have to) -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: mapreduce-issues-unsubscribe@hadoop.apache.org For additional commands, e-mail: mapreduce-issues-help@hadoop.apache.org
