Eric Yang updated HDDS-1520:
----------------------------
Description:
[~eyang] reported that the ozone can't be started if the ozone directory is
symlinked due to the classpath assembly. It should work even if the directory
is symlinked.
Ozone script generates CLASSPATH environment variable based on parsing of
ozone-0.5.0-SNAPSHOT/share/ozone/classpath/*.classpath file, then substitute
HDDS_LIB_JARS_DIR with OZONE_HOME/share/ozone/lib. When OZONE_HOME directory
path has a long prefix, this can cause CLASSPATH environment variable to exceed
string length limit set for a single environment variable. This cause Ozone
command to return random errors with class not found exception.
