> sqenvcom.sh sets up CLASSPATH for trafodion.
> With HDP2.2, this CLASSPATH is huge.   On one of our system, echo $CLASSPATH | wc -l return > 13000 bytes.
> I believe java/Linux truncates these variables when it's too big.
> Since going to HDP 2.2, we've been hit with "class not found" error eventhough the jar is in CLASSPATH.
> http://stackoverflow.com/questions/1237093/using-wildcard-for-classpath explains that we can use wildcards in CLASSPATH to reduce it.
> Rules:
> Use * and not *.jar.    Java assumes that * in classpath are for *.jar
> When using export CLASSPATH    use quotes so that * is not expanded.   EG:    export CLASSPATH=”/usr/hdp/current/hadoop-client/lib/*:${CLASSPATH}”
> We need to modify our sqenvcom.sh to use wildcards instead of putting individual jar.
