Streamsets version from CLI - streamsets

Question

I'm currently writing code that locally installs streamsets extensions via a CLI. One of the checks I want to write is to ensure that the extension works for the streamsets version that's installed locally.
When I try to query the version from the CLI this is what I run into.
:) streamsets --version
Invalid sub-command
streamsets <SUB_COMMAND> [<SUB_COMMAND_ARGUMENTS>]
Sub-commands:
dc: Starts the Data Collector
create-dc: Creates new instance of Data Collector
cli: Data Collector CLI
jks-cs: Java Keystore Credential Store
stagelibs: Data Collector Stage library installer
show-vault-id: Shows the user-id to authorize in Vault
setup-mapr: Enables the MapR stage library for the detected
MapR installation.
:( streamsets cli --version
Found unexpected parameters: [--version]
) streamsets dc --version
Invalid option(s)
streamsets dc <OPTIONS>
Options:
-verbose : prints out Data Collector detailed environment settings
-exec : starts Data Collector JVM within the same process of the script
-skipenvsourcing : skips the sourcing of the libexec/sdc-env.sh file
How do I figure out what version of streamsets is installed other than traversing the file system and finding the VERSION file?

Answer 1

You can get a Data Collector's info, including the version, with the CLI's ping command:
$ streamsets cli -U http://localhost:18630 ping
{
"info" : {
"built.date" : "2018-06-13T23:02Z",
"version" : "3.4.0-SNAPSHOT",
"built.repo.sha" : "9f803ed0f5167bbb91af2493b20c9a20b566106f",
"source.md5.checksum" : "1d59dbb2281a974f4b192a28efe7624c",
"built.by" : "pat"
},
"version" : "3.4.0-SNAPSHOT",
"builtDate" : "2018-06-13T23:02Z",
"builtBy" : "pat",
"builtRepoSha" : "9f803ed0f5167bbb91af2493b20c9a20b566106f",
"sourceMd5Checksum" : "1d59dbb2281a974f4b192a28efe7624c"
}
system info is a synonym for ping
This isn't (yet) documented. I'll open a doc Jira to do so.
