Aryan Gupta updated HDDS-15912:
-------------------------------
Description:
HttpFS launcher currently sets {{httpfs.log.dir}} and {{httpfs.temp.dir}} under
{{OZONE_HOME}} ({{{}${OZONE_HOME}/log{}}}, {{{}${OZONE_HOME}/temp{}}}).
{{HttpFSServerWebApp}} initializes through {{{}ServerWebApp{}}}, and
{{Server.init()}} validates these directories at startup. If
{{${OZONE_HOME}/temp}} is missing, startup fails with {{{}S01: Dir .../temp
does not exist{}}}, and Jetty stops the connector.
Fix: switch launcher defaults to runtime-managed directories:
* {{httpfs.log.dir=${OZONE_LOG_DIR}}}
* {{httpfs.temp.dir=${OZONE_PID_DIR}}}
This removes dependency on install-tree temp/log paths and makes HttpFS startup
more robust across deployment layouts.
was:
HttpFS startup can fail in parcel deployments because the launcher sets
{{httpfs.log.dir}} and {{httpfs.temp.dir}} under {{OZONE_HOME}}
({{{}${OZONE_HOME}/log{}}}, {{{}${OZONE_HOME}/temp{}}}). {{HttpFSServerWebApp}}
still initializes through {{{}ServerWebApp{}}}, and {{Server.init()}} validates
these directories. If {{${OZONE_HOME}/temp}} is missing, startup fails with
{{{}S01: Dir .../temp does not exist{}}}, and Jetty stops the connector, making
the HttpFS port unavailable.
Fix is to use runtime-managed launcher directories instead:
* {{httpfs.log.dir=${OZONE_LOG_DIR}}}
* {{httpfs.temp.dir=${OZONE_PID_DIR}}}
This avoids mutable runtime paths under install directory and keeps HttpFS
startup stable across parcel/CM environments.
