Description

The classpath is created assuming the native-client is a module of the parent hbase repo. Since that is not the case anymore and we rely on a dynamically pulled HBase version, we need to fix the classpath for the JVM that is spun using JNI. Otherwise mini-cluster won't start..

using hbase::MiniCluster;

JNIEnv *MiniCluster::CreateVM(JavaVM **jvm) {
  JavaVMInitArgs args;
  JavaVMOption jvm_options;
  args.version = JNI_VERSION_1_6;
  args.nOptions = 1;
  char *classpath = getenv("CLASSPATH");
  std::string clspath;
  if (classpath == NULL || strstr(classpath, "-tests.jar") == NULL) {
    std::string clsPathFilePath("../../../hbase-build-configuration/target/cached_classpath.txt");
    std::ifstream fd(clsPathFilePath);
    std::string prefix("");
    if (fd.is_open()) {
      if (classpath == NULL) {
        LOG(INFO) << "got empty classpath";
      } else {
        // prefix bootstrapper.jar
        prefix.assign(classpath);
      }
      std::string line;
