Thank you for your reply Vincent. We don't use Redhat. We are on Ubuntu and we use Cloudera Parcels for installation. Is there a way to build debug symbols from the parcel package?
I just confirmed that the source I build if for the same git tag/hash, so I am still puzzled why the symbols don't show up: root@cloudera-worker-beef-eb891d7e:/opt/cloudera/parcels/CDH-5.10.0-1.cdh5.10.0.p0.41/lib/impala/sbin-retail# impalad --version impalad version 2.7.0-cdh5.10.0 RELEASE (build *785a073cd07e2540d521ecebb8b38161ccbd2aa2*) Built on Fri Jan 20 12:03:56 PST 2017 On Thu, Feb 8, 2018 at 8:46 PM Vincent Tran <[email protected]> wrote: > Looks like the hash of the symbols from your build does not match the one > in the minidump. > > Can you try to pull the symbols from the rpms and try again? > I've only used the symbols from local builds on minidumps generated by the > same minicluster.
