[jira] [Created] (HDFS-12545) Autotune NameNode RPC handler threads according to number of datanodes in cluster
Ajay Kumar created HDFS-12545: - Summary: Autotune NameNode RPC handler threads according to number of datanodes in cluster Key: HDFS-12545 URL: https://issues.apache.org/jira/browse/HDFS-12545 Project: Hadoop HDFS Issue Type: Improvement Reporter: Ajay Kumar Assignee: Ajay Kumar Autotune NameNode RPC handler threads according to number of datanodes in cluster. Currently rpc handler are controlled by {{dfs.namenode.handler.count}} on cluster start. Jira is to discuss best way to auto tune it according to no of datanodes. Updating this to {{max(dfs.namenode.handler.count, min(200,20 * log2(no of datanodes)))}} on NameNode start is one possible way. -- This message was sent by Atlassian JIRA (v6.4.14#64029) - To unsubscribe, e-mail: hdfs-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-dev-h...@hadoop.apache.org
HDFS NN FSNamesystemLock throughput
Hi, guys, Recently we're looking into HDFS NameNode FSNamesystemLock implementation. As it uses Java's ReentrantReadWriteLock, after configing the lock to nonfair mode, the RPC throughput has been improved a lot. Just wonder whether anyboby have played around the reader/writer preference further in the lock (or directly used another lock implementation) to achieve higher throughput, absolutely there will be trade-off between throughput and write starvation. thanks, Wei
[jira] [Created] (HDFS-12544) SnapshotDiff - support diff generation on any snapshot root descendant directory
Manoj Govindassamy created HDFS-12544: - Summary: SnapshotDiff - support diff generation on any snapshot root descendant directory Key: HDFS-12544 URL: https://issues.apache.org/jira/browse/HDFS-12544 Project: Hadoop HDFS Issue Type: Improvement Components: hdfs Affects Versions: 3.0.0-beta1 Reporter: Manoj Govindassamy Assignee: Manoj Govindassamy {noformat} # hdfs snapshotDiff {noformat} Using snapshot diff command, we can generate a diff report between any two given snapshots under a snapshot root directory. The command today only accepts the path that is a snapshot root. There are many deployments where the snapshot root is configured at the higher level directory but the diff report needed is only for a specific directory under the snapshot root. In these cases, the diff report can be filtered for changes pertaining to the directory we are interested in. But when the snapshot root directory is very huge, the snapshot diff report generation can take minutes even if we are interested to know the changes only in a small directory. So, it would be highly performant if the diff report calculation can be limited to the snapshot directory only instead of the whole snapshot root. -- This message was sent by Atlassian JIRA (v6.4.14#64029) - To unsubscribe, e-mail: hdfs-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-dev-h...@hadoop.apache.org
[jira] [Created] (HDFS-12543) Ozone : allow create key without specifying size
Chen Liang created HDFS-12543: - Summary: Ozone : allow create key without specifying size Key: HDFS-12543 URL: https://issues.apache.org/jira/browse/HDFS-12543 Project: Hadoop HDFS Issue Type: Improvement Reporter: Chen Liang Assignee: Chen Liang Currently when creating a key, it is required to specify the total size of the key. This makes it inconvenient for the case where a key is created and data keeps coming and being appended. This JIRA is remove the requirement of specifying the size on key creation, and allows appending to the key indefinitely. -- This message was sent by Atlassian JIRA (v6.4.14#64029) - To unsubscribe, e-mail: hdfs-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-dev-h...@hadoop.apache.org
