Hi Team, I am trying to troubleshoot a SIGSEGV crash we are getting with Impala 2.7 frequently. I followed the instructions here:
https://cwiki.apache.org/confluence/display/IMPALA/Debugging+Impala+Minidumps However, it seems symboles are not resolving when I try to extract them with minidump_stackwalk. Here are the details: CDH5.10.0 Impala 2.7 build 785a073cd07e2540d521ecebb8b38161ccbd2aa2 What I have done is the following: - clone Cloudera/Impala from github - checkout 785a073cd07e2540d521ecebb8b38161ccbd2aa2 - ./configure - make - ./bin/dump_breakpad_symbols.py -b be/build/latest -d ~/impala-syms --dump_syms ./toolchain/breakpad-20150612-p1/bin/dump_syms - ./toolchain/breakpad-20150612-p1/bin/minidump_stackwalk ~/034329c7-9088-0fa3-3fb76e38-2f2208f5.dmp ~/impala-syms > ~/resolved.txt However, symbols aren't resolved. If I look at the end of resolved.txt I see this: Loaded modules: 0x00400000 - 0x02830fff impalad ??? (main) (WARNING: No symbols, impalad, 51659402847B9CA647AB6C35F403A7EB0) 0x7f6071517000 - 0x7f6071725fff libudfsample.64523.0.so ??? 0x7f60fd341000 - 0x7f60fd559fff libresolv-2.19.so ??? 0x7f60fd55c000 - 0x7f60fd761fff libnss_dns-2.19.so ??? .... I have repeated the process many time to confirm I am not making a mistake following the steps, but I might be missing something. Your advise is greatly appreciated. Cheers, -Arya
