<!-- Supplies org.apache.hadoop.fs.obs.OBSFileSystem. Nothing here calls it: this module reaches OBS

through the native esdk SDK above, and the ONLY reference is the initialize=false

Class.forName probe in ObsFileSystemProperties, which decides whether toHadoopConfigurationMap

emits fs.obs.impl=OBSFileSystem or falls back to fs.obs.impl=S3AFileSystem. The probe resolves

against THIS module's own classloader, so the jar has to sit in this plugin for the probe to

tell the truth. Consumers that actually instantiate the class carry their own copy

(fe-connector-paimon, be-java-extensions/hadoop-deps); fe-connector-iceberg needs none because

it normalizes obs:// to s3 and goes through S3AFileSystem.

runtime scope keeps it off the compile classpath; plugin-zip.xml packs the runtime closure.

com/obs/* DUPLICATION — read before touching versions or artifact names. The -hw-46 jar is a

fat jar that inlines the whole esdk SDK (762 com/obs/* classes, identical to the

esdk-obs-java-optimised 3.21.8.2 content), and esdk-obs-java-bundle above ships 511 of which

510 collide. That is TWO copies of com.obs.services.ObsClient in this plugin's lib/, at

DIFFERENT versions (3.21.11 declared above vs 3.21.8.2 inlined here), and ObsObjStorage

compiles against the former. DirectoryPluginRuntimeManager.collectJars sorts lib/ jars

lexicographically, so "esdk-obs-java-bundle-*" precedes "hadoop-huaweicloud-*" and the

declared 3.21.11 wins — correct, but only because of that ordering. If either artifact is

renamed or the esdk coordinates change, re-check that the bundle still sorts first.

The transitive esdk-obs-java-optimised is excluded below: it is a third, redundant copy of

the same classes already inlined in the fat jar, and the only one that could shadow the

declared bundle if the sort order ever shifted.

NOTE: the -hw-46 artifact is NOT in Maven Central; it comes from the huawei-obs-sdk repo

declared in <repositories> below (fe-connector-paimon declares the same repo for the same dep). -->
