I am new to ES and have inherited work to upgrade from ES 5.5 to ES 6.5
What happened to /usr/share/elasticsearch/bin/elasticsearch.in.sh in the ES 6.5 rpm?
I see it present in ES 5.5 rpm.
As part of the build process for the product I work on we have a line in our rpm spec file %post:
echo 'ES\_JAVA\_OPTS="$ES\_JAVA\_OPTS -Xms2g -Xmx2g"' \>\> /usr/share/elasticsearch/bin/elasticsearch.in.sh
What was this file responsible for and where did it go? I don't think this is a breaking change for what I'm doing (not listed in breaking changes) but I would like to know 🙂
