I have gotten log output out of htrace4-core in Hadoop. I used the line: > log4j.rootLogger=TRACE,file,console
commons-logging is a kind of shim which is (usually but not always) on top of log4j. Perhaps try modifying your log4j settings? Unfortunately it's hard to give good advice about log4j since there are so many configurations. One thing that helps sometimes is using strace to find out which log4j.properties file it's really opening. best, Colin On Mon, May 16, 2016, at 21:02, Lewis John Mcgibbney wrote: > Hi Folks, > So I consume htrace-core4 in the Nuch Java application.
