Solr Permission denied with OpenLDAP + Open-Source Ranger example about ranger-emr-cli-installer

hi @heng2j , it seems your host has no enough memory to start solr. it is recommended that 4 vCore / 16 GB or above.

The issue may not due to permissions, since I just changed the permissions for the entire /opt/solr/ folder.

By looking at the /var/log/solr/ranger_audits/solr-8983-console.log the issue may due to lack of memory in my t2.micro instance.

OpenJDK 64-Bit Server VM warning: INFO: os::commit_memory(0x00000000a0000000, 1610612736, 0) failed; error='Cannot allocate memory' (errno=12)
#
# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (mmap) failed to map 1610612736 bytes for committing reserved memory.

Yes indeed @bluishglc! Thank you for your confirmation.
