Hi all!

Been trying to install hail (https://hail.is/) on databricks with no luck so far. Is there an easy way to make it work? So far I could not get further than (providing sparkContext like `hl.init(sc=spark.sparkContext` also did not help):

import hail as hl
hl.init()
TypeError: 'JavaPackage' object is not callable
File <command-3243506661262167>, line 3
      1 import hail
      2 get_ipython().system('echo $JAVA_HOME')
----> 3 hail.init_spark()
File /databricks/python/lib/python3.11/site-packages/hail/backend/spark_backend.py:130, in SparkBackend.__init__(self, idempotent, sc, spark_conf, app_name, master, local, log, quiet, append, min_block_size, branching_factor, tmpdir, local_tmpdir, skip_logging_configuration, optimizer_iterations, gcs_requester_pays_project, gcs_requester_pays_buckets, copy_log_on_error)
    128     jhc = hail_package.HailContext.getOrCreate(jbackend, branching_factor, optimizer_iterations)
    129 else:
--> 130     jbackend = hail_package.backend.spark.SparkBackend.apply(
    131         jsc,
    132         app_name,
    133         master,
    134         local,
    135         log,
    136         True,
    137         append,
    138         skip_logging_configuration,
    139         min_block_size,
    140         tmpdir,
    141         local_tmpdir,
    142         gcs_requester_pays_project,
    143         gcs_requester_pays_buckets,
    144     )
    145     jhc = hail_package.HailContext.apply(jbackend, branching_factor, optimizer_iterations)
    147 self._jsc = jbackend.sc()

Cheers!
