Java Indexer failed to index project

[CaoGaorong]

I have compiled the glean from source code and built the Java Indexer. But when I index the Java proejct, it reports error:

*** Exception: basic-thriftservice does not support Tier
CallStack (from HasCallStack):
  error, called at glean/util/Glean/Impl/ThriftService.hs:98:25 in glean-0.1.0.0-l-util-63572f97e9c1b8d79e35c8d87fea30a67c6904aa6152962ada96215ef7135341:Glean.Impl.ThriftService

Here is my steps:

1. build the Glean (Everything works fine)

-- Installing: /root/.hsthrift/lib/cmake/rocksdb/RocksDBConfig.cmake
-- Installing: /root/.hsthrift/lib/cmake/rocksdb/RocksDBConfigVersion.cmake
-- Installing: /root/.hsthrift/lib/pkgconfig/rocksdb.pc
export LD_LIBRARY_PATH=/root/.hsthrift/lib
export PKG_CONFIG_PATH=/root/.hsthrift/lib/pkgconfig
export PATH=$PATH:/root/.hsthrift/bin

2. run the Java indexer

@#cabal build exe:glean
Up to date

As above shown, the java indexer is works good.

3. index the Java project(change to the project dir and run the following command):

@#glean index java-lsif ./ --db wdappser/wdappserInstance
glean: basic-thriftservice does not support Tier
CallStack (from HasCallStack):

or index in the shell:

@#glean shell

I had rebuilt the Glean but it still not works. Is there any solution or suguestion to solve this? Or why does it reports "Exception: basic-thriftservice does not support Tier"? Any help would be greatly appreciated!

You need to supply either --db-root <dir> to use local DBs, or start a Glean server and use --service <host>:<port> to connect to the server. Failure to do one of these things leads to the basic-thriftservice does not support Tier error message. It's a terrible error message and we need to improve it!

A bit of background for where the error comes from: the Glean config is set up to connect to a default service if one isn't supplied. Internally at Meta a service is called a "tier", but in the open source build there's no way to resolve a tier to a host and port, hence the error message.

This should fix the error message: #577
