!pip install h2o_pysparkling_3.5
from pysparkling import H2OConf,H2OContext
conf = H2OConf().set('spark.dynamicAllocation.enabled', False)
hc = H2OContext.getOrCreate(conf)

I am getting the below error
IllegalArgumentException: Unsupported argument: (spark.speculation,true)

I tried spark.conf.set("spark.speculation", "false"), But the below error came for this
[CANNOT_MODIFY_CONFIG] Cannot modify the value of the Spark config: “spark.speculation”.
