I like the lazy eval style

thread safety: what is the story here?
what's the story w.r.t IOExceptions being raised in the init function?

in org.apache.hadoop.fs.impl.FunctionsRaisingIOE we have an interface for functions which explicilty raise them. Using that or something like it makes sense here

Thanks @steveloughran for the review.
I have incorporated FunctionsRaisingIOE to take care of IOException. Thanks for the pointer. Also added synchronized block around initialization of file system instance.

Someone else needs to review the core functionality, but I like the changes. Still need to get that sync block right though. FWIW, long init has caused problems with Hive in the past, hence work in s3a to try and reduce the amount of network IO here. Lazy init too hard work to justify though

this will dual init as thread #2 will block. You need another check inside the sync block so the second thread won't repeat itself

Added extra check

FYI. I've got a WrappedIOException, but in #2069 making it a public org.apache.hadoop.fs.functional.RuntimeIOException whose cause is only ever IOE. Not something to be picked up here (yet), but worth knowing. I'm trying to make the functional & lambda/expression stuff more useable,

umamaheswararao · 2020-09-04T17:15:32Z

Thanks @steveloughran for review!
In addition to his comments, I have the following question/comment.
In practice, I am thinking this lazy initialization will not give us real benefit in the following case with MR/YARN.
In DelegationTokenIssuer#collectDelegationTokens, it will try to get tokens from all children.

// Now collect the tokens from the children.
    final DelegationTokenIssuer[] ancillary =
        issuer.getAdditionalTokenIssuers();
    if (ancillary != null) {
      for (DelegationTokenIssuer subIssuer : ancillary) {
        collectDelegationTokens(subIssuer, renewer, credentials, tokens);
      }
    }

I am wondering this call will make all fs to be initialized. That means we are not getting this lazy initialization benefit fully.
Did you consider this case?
Is there a way to avoid this ? MR/YARN team can suggest something if we have alternative way to load tokens.

@umamaheswararao @steveloughran bumping up the conversation on this thread. Recently we have faced lot of issues (OOM, fs initialization time going up) because of not having lazy initialization.
We see these issues where we have 10k mount points and ViewFileSystem initializes all the mount points during initialization.
Want to get a review on this one.

It looks like @steveloughran deprecated this class later after his comment. Don't know what prompted the refactoring, but
import org.apache.hadoop.fs.impl.FunctionsRaisingIOE.FunctionRaisingIOE
should be now
org.apache.hadoop.util.functional.FunctionRaisingIOE

replaced org.apache.hadoop.fs.impl.FunctionsRaisingIOE.FunctionRaisingIOE with org.apache.hadoop.util.functional.FunctionRaisingIOE

You can call closeAll() here, which clears the cache completely. And the you can compare with 0 in the assert.

Looks good generally. I checked the tests are catching previous errors.

There seems to be one last checkstyle warning.
Also I see you use import static org.junit.Assert.*; and viewfs.Constants.*; We should import only what is actually needed. Avoid *-imports.
And I found an empty line added in ViewFileSystem. Don't know why checkstyle didn't catch it.

@shvachko I have removed the checkstyle warning. Also added the individual imports and removed the empty line
