在root權(quán)限下jmap -dump:format=b,file=/tmp/driver.hprof 79206 spark driver 總是提示
Unable to open socket file: target process not responding or HotSpot VM not loaded
The -F option can be used when the target process is not responding
這個(gè)時(shí)候發(fā)現(xiàn)pid 79206 不在/tmp/hsperfdata_root下锋叨。而是在/tmp/hsperfdata_yarn下，所以在yarn賬號(hào)下執(zhí)行就好了
