Subject [jira] [Commented] (HADOOP-10728) Metrics system for Windows Azure Storage Filesystem
Date Tue, 24 Jun 2014 17:17:24 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-10728?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14042390#comment-14042390

Chris Nauroth commented on HADOOP-10728:
----------------------------------------

[~mikeliddell], thanks for the new patch.  I verified that tests pass for me, in both stubbed
mode and integrated with the real service.  This is really close now.  Just a few more things:
# We need one more Apache license header on hadoop-metrics2-azure-file-system.properties.
# In pom.xml, if you want to include everything in src/test/resources, then we can actually
remove the whole {{<testResources>}} stanza.  Maven's default is to include everything
from src/test/resources if {{<testResources>}} isn't specified.

> Add a metrics2 source for the Windows Azure Filesystem driver that was introduced with
HADOOP-9629.
> AzureFileSystemInstrumentation is the new MetricsSource.

and some machinery is added for the accumulation of 'rolling average' statistics.
> Primary new code appears in org.apache.hadoop.fs.azure.metrics namespace.
> h2. Credits and history
> Credit for this work goes to the early team: [~minwei], [~davidlao], [~lengningliu] and
[~stojanovic] as well as multiple people who have taken over this work since then (hope I
don't forget anyone): [~dexterb], Johannes Klein, [~ivanmi], Michael Rys, [~mostafae], [~brian_swan],
[~mikelid], [~xifang], and [~chuanliu].
