Colin Patrick McCabe commented on HADOOP-12201:
-----------------------------------------------
Thanks, Brahma. createFileSystem generally happens only once and it seems to
take a long time (about a second), so it seems like a great candidate for
tracing. Globber#glob also can be time-consuming so there is value in tracing
it. I've been looking at a lot of FsShell traces lately and this came out of
that.
