We are installing hdp 2.5.3. on SLES 12 SP2 64 bit in a single node environment. Installation went fine with a couple of adjustments but we can't start the data node as it stops with the following message. We executed execstack but didnt receive any reply of the program and the error remains. We checked a couple of posts similar to the one we are observing, but we couldn't fix it so far.
Execution of 'ambari-sudo.sh su hdfs -l -s /bin/bash -c 'ulimit -c unlimited ; /usr/hdp/current/hadoop-client/sbin/hadoop-daemon.sh --config /usr/hdp/current/hadoop-client/conf start datanode'' returned 1. starting datanode, logging to /var/log/hadoop/hdfs/hadoop-hdfs-datanode-hadoop26.out
Java HotSpot(TM) Server VM warning: You have loaded library /usr/hdp/220.127.116.11-37/hadoop/lib/native/libhadoop.so.1.0.0 which might have disabled stack guard. The VM will try to fix the stack guard now.
It's highly recommended that you fix the library with 'execstack -c <libfile>', or link it with '-z noexecstack'.
