It's not structured support, which is why we don't use purely open-source projects without additional structured support.
I have received support via newsgroups or guidance on specific discussions, which is what I would expect in an open-source situation.
It is a distributed file system and scales reasonably well as long as it is given sufficient resources.
Continuous management in the way of upgrades and technical management is necessary to ensure that it remains effective.
Apache Spark resolves many problems in the MapReduce solution and Hadoop, such as the inability to run effective Python or machine learning algorithms.
Without a doubt, we have had some crashes because each situation is different, and while the prototype in my environment is stable, we do not know everything at other customer sites.
The problem with Apache Hadoop arose when the guys that originally set it up left the firm, and the group that later owned it didn't have enough technical resources to properly maintain it.
Various tools like Informatica, TIBCO, or Talend offer specific aspects, licensing can be costly;
I assess Apache Hadoop's fault tolerance during hardware failures positively since we have hardware failover, which works without problems.
Hadoop is a distributed file system, and it scales reasonably well provided you give it sufficient resources.
Not all solutions can make this data fast enough to be used, except for solutions such as Apache Spark Structured Streaming.
The solution is beneficial in that it provides a base-level long-held understanding of the framework that is not variant day by day, which is very helpful in my prototyping activity as an architect trying to assess Apache Spark, Great Expectations, and Vault-based solutions versus those proposed by clients like TIBCO or Informatica.

Spark provides programmers with an application programming interface centered on a data structure called the resilient distributed dataset (RDD), a read-only multiset of data items distributed over a cluster of machines, that is maintained in a fault-tolerant way. It was developed in response to limitations in the MapReduce cluster computing paradigm, which forces a particular linear dataflowstructure on distributed programs: MapReduce programs read input data from disk, map a function across the data, reduce the results of the map, and store reduction results on disk. Spark's RDDs function as a working set for distributed programs that offers a (deliberately) restricted form of distributed shared memory
