Hi,
Just noticed that [1] (and also [3]) is very cautious with $ and $$ to
expand environment variables.
javaOpts += "-Djava.io.tmpdir=" +
new Path(
YarnSparkHadoopUtil.expandEnvironment(Environment.PWD), // <-- here
YarnConfiguration.DEFAULT_CONTAINER_TEMP_DIR
)
Few lines below in the same method [2] the code doesn't seem to bother
to call $ directly :
Client.buildPath(Environment.PWD.$(), uri.getPath())
Why? Any particular reason for the difference in the two lines? #curious
