-
rename wrappers to something less generic (helps prevent namespace collisions)
- 34. By Kevin W Monroe
-
move m2 logic to snapcraft.yaml; use SNAP_COMMON for pid dirs; add configure hook to ensure dirs are always available
- 33. By Kevin W Monroe
-
simplify patches (we have our own wrappers; no need to patch install); move the m2 settings patch into snapcraft.yaml
- 31. By Kevin W Monroe
-
add mapred pseudo config; change hadoop-conf slot to write; all hadoopy snaps should now look for config in $snap_data
- 28. By Kevin W Monroe
-
combine daemons, use install vs configure hook
- hdfs/mapred/yarn daemons do almost the same thing; make a single
wrapper figure out the right task based on args.- the configure hook runs *after* systemctl services. we need
something earlier to setup snap_data, so do it in the install hook.- tweak sed logic in install hook to ensure we change right values.
- tweak error/warning messages in our wrappers.
- snapcraft.yaml changes:
- remove unused hadoop /etc/default bits (covered by common-wrapper).
- bump to snap5. - 26. By Kevin W Monroe
-
hook and wrapper work to support hadoop daemons
- add yarn config to configure hook
- if we have a pseudo cluster, format the NN with the configure hook
to lessen user burden (requires the hook to have the network plug)- add network[-bind] to all hadoop apps and daemons since they all
do java network activity- add 5 hadoop daemons (2 hdfs, 2 yarn, 1 jobhistory)
- be more explicit about errors vs warnings in our wrappers
