-----------------------------------
Summary: Use PathCapabilities for default configuring append mode
for RollingFileSystemSink
Key: HADOOP-16713
URL: https://issues.apache.org/jira/browse/HADOOP-16713
Project: Hadoop Common
Issue Type: Bug
Components: metrics
Affects Versions: 3.3.0
Reporter: Adam Antal
{{RollingFileSystemSink}} uses a filesystem to store metrics. The key
{{allow-append}} is disabled by default, but if enabled, new metrics can be
appended to an existing file.
Given that we can have the {{PathCapabilities}} interface, we can change the
default of {{allow-append}} mode depending on the support of the append
operation decided by the {{FileSystem.hasPathCapability()}} call
