ASF GitHub Bot commented on HADOOP-18671: ----------------------------------------- taklwu opened a new pull request, #5553: URL: https://github.com/apache/hadoop/pull/5553 ### Description of PR Propagating the recoverLease, setSafeMode, isFileClosed functions to separate interface as well as introducing new path capabilities ### How was this patch tested? 1. tested with the hadoop-aws contract test for against us-west-2 on S3 2. ran unit test for hdfs ### For code changes: - [X] Does the title or this PR starts with the corresponding JIRA issue id (e.g. 'HADOOP-17799. Your PR title ...')? - [X] Object storage: have the integration tests been executed and the endpoint declared according to the connector-specific documentation? - [ ] If adding new dependencies to the code, are these dependencies licensed in a way that is compatible for inclusion under [ASF 2.0](http://www.apache.org/legal/resolved.html#category-a)? - [ ] If applicable, have you updated the `LICENSE`, `LICENSE-binary`, `NOTICE-binary` files? > Add recoverLease(), setSafeMode(), isFileClosed() APIs to FileSystem > -------------------------------------------------------------------- > > Key: HADOOP-18671 > URL: https://issues.apache.org/jira/browse/HADOOP-18671 > Project: Hadoop Common > Issue Type: New Feature > Components: fs > Reporter: Wei-Chiu Chuang > Priority: Major > > We are in the midst of enabling HBase and Solr to run on Ozone. > An obstacle is that HBase relies heavily on HDFS APIs and semantics for its > Write Ahead Log (WAL) file (similarly, for Solr's transaction log). We > propose to push up these HDFS APIs, i.e. recoverLease(), setSafeMode(), > isFileClosed() to FileSystem abstraction so that HBase and other applications > do not need to take on Ozone dependency at compile time. This work will > (hopefully) enable HBase to run on other storage system implementations in > the future. > There are other HDFS features that HBase uses, including hedged read and > favored nodes. Those are FS-specific optimizations and are not critical to > enable HBase on Ozone. -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-issues-h...@hadoop.apache.org
