gaia-dmp's Issues

Load path for Hadoop native libraries

Ansible installed system is unable to find the native libraries for Hadoop.

pyspark
    ....
    2020-04-20 13:05:41,559 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable
    ....

Possible solution is to add one of the following:

export HADOOP_COMMON_LIB_NATIVE_DIR=$HADOOP_HOME/lib/native
export HADOOP_OPTS="-Djava.library.path=$HADOOP_HOME/lib"

See https://stackoverflow.com/a/24854346

Flag to skip live host test

If we are restarting everything after a power cut, there is no live service to poll.

source /deployments/hadoop-yarn/bin/deploy.sh

    ssh: connect to host live.gaia-dmp.uk port 22: Connection refused
    ....
    ....

We need to wrap this with a command line option that skips the test.

gaia-dmp/deployments/hadoop-yarn/bin/deploy.sh

Lines 25 to 34 in 7855dca

live_hostname=$(ssh -o "StrictHostKeyChecking no" [email protected] 'hostname')
if [[ "$live_hostname" == *"$cloudname"* ]]; then
read -p "You are replacing the current live system!! Do you want to proceed? (y/N) " -n 1 -r
echo
if [[ $REPLY != "y" ]];
then
exit
