> Key: FLINK-5207
> URL: https://issues.apache.org/jira/browse/FLINK-5207
> Project: Flink

> Reporter: Ufuk Celebi
> Fix For: 1.2.0, 1.1.4

>
> HadoopFileSystem logging is very noisy when trying to get the Hadoop
> configuration, which happens for every HadoopFileSystem. This happens for
> example when a checkpoint is written to HDFS in case of HA.
> 1) Two log messages relate to the user config:
> {code}
> final String hdfsDefaultPath =
> GlobalConfiguration.getString(ConfigConstants.HDFS_DEFAULT_CONFIG, null);
> if (hdfsDefaultPath != null) {
> retConf.addResource(new
> org.apache.hadoop.fs.Path(hdfsDefaultPath));
> } else {
> LOG.debug("Cannot find hdfs-default configuration
> file");
> }
> {code}
> Since this is reflected in the logged configuration properties, it is mostly
> unnecessary to log over and over again. Therefore I propose to go with TRACE.
> (2) Two log messages relate to the default config files of Hadoop. There I
> would change the debug message to happen only when they are *not* found. If
> it is still too noisy, we could completely remove it or decrease to TRACE at
> another time.
