Veena Basavaraj commented on SQOOP-1623:
----------------------------------------
Digging deeper here is the answer on how this all works.
sqoop-common package does a bit of magic generating the{code}
VersionAnnotation{code} class as part of building the sqoop-common package.
This annotation information is used in {code}Versionifo{code} class that gets
the current build version of the sqoop-common.
The VersionInfoBean also uses the same technique underneath.
Next, if we see the client/shell that print outs the versions for client and
then the server.
{code}
// Print out client string if needed
if (client) {
printlnResource(Constants.RES_SHOW_PROMPT_VERSION_CLIENT_SERVER,
Constants.OPT_CLIENT,
// See SQOOP-1623 to understand how the client version is derived.
VersionInfo.getBuildVersion(),
VersionInfo.getSourceRevision(),
VersionInfo.getUser(),
VersionInfo.getBuildDate()
);
}
// If only client version was required we do not need to continue
if(!server && !restApi) {
return;
}
if (versionRequest == null) {
versionRequest = new VersionResourceRequest();
}
VersionBean versionBean = versionRequest.read(getServerUrl());
if (server) {
printlnResource(Constants.RES_SHOW_PROMPT_VERSION_CLIENT_SERVER,
Constants.OPT_SERVER,
versionBean.getBuildVersion(),
versionBean.getSourceRevision(),
versionBean.getSystemUser(),
versionBean.getBuildDate()
);
}
{code}
The client version literally means the version of the sqoop common jar embedded
in the client.
The server version is then got from the REST api. As a result it will use the
sqoop common jar version that the server was built with

> Currently the sqoop client version is the same as the server version and it

> The client and server can be release independently and hence they can be

> saveVersion.sh equivalent is required for the sqoop client as well
