Re: Configuring ignite distributed hibernate cache

[Denis Magda]

Val,

Can we add this workaround to our documentation by creating an “attention” 
block? The block can be removed once the issue is fixed for binary marshaller.

Excellent, that did the trick!  Thanks a lot for the help.

Re: How to avoid the event lost in the continuous query

[vkulichenko]

Remote filter is on server nodes, local listener is on the client. Here is an
example:

BTW, as a workaround you can try switching to OptimizedMarshaller. Add this
to your Ignite config:





Let me know if it works.

Re: Configuring ignite distributed hibernate cache

Hi,

Most likely this is caused by this issue:
https://issues.apache.org/jira/browse/IGNITE-3429. Hopefully, someone in the
community will pick it up and fix.

Configuring ignite distributed hibernate cache

[Himetic]

I'm using the hibernate caching ignite provides (as documented here:
https://apacheignite.readme.io/docs/hibernate-l2-cache) and having some
difficulty getting the caching to work in a distributed manner.  It works
fine when the object is cached locally, and it seems to be aware of the
other machine (in the logs it prints:

Metrics for local node (to disable set 'metricsLogFrequency' to 0)
^-- Node [id=5ae49faa, name=hibernate-grid, uptime=00:01:00:000]
^-- *H/N/C [hosts=2, nodes=2, CPUs=16]*
^-- CPU [cur=0.53%, avg=9.92%, GC=0%]
^-- Heap [used=986MB, free=45.84%, comm=1597MB]
^-- Non heap [used=146MB, free=-1%, comm=150MB]
^-- Public thread pool [active=0, idle=16, qSize=0]
^-- System thread pool [active=0, idle=16, qSize=0]
^-- Outbound messages queue [size=0]

when we start up the second machine, which seems to indicate that it's
reaching the second machine, at least in some capacity.  But when we perform
a GET on one machine, and then on the other, the second machine isn't
hitting the cached value.

I believe we've got it set up for partitioned caching across the hosts. 
Here's the xml for the hosts:










[IP addr 1]:48500..48520
[IP addr 2]:48500..48520







Each of the caches is set up to extend the transactional parent from the
documentation:







As I said, the cache itself IS working locally, but it doesn't seem to
actually be partitioning it.  I debugged into the cache retrieval method and
it's going through GridCacheAdapter in Ignite, but ultimately not finding
the value that's supposed to cached already from making the call on the
other machine.  Is there something wrong with our configuration?  Or is
there some other step I missed?  Thanks!

Getting a cluster-configured JCache CacheManager instance

[Josh Cummings]

I would like to get an instance of a JCache CacheManager that is configured
to point at a remote Ignite cluster.

I understand that I can provide a location to a spring configuration file
with the correct discovery strategy, etc.; however, it appears that in that
strategy I must supply an IP address directly in the file.

All our configuration is housed centrally, so I cannot provide the
IP address directly in the file.

1. What options are there for doing property placeholder resolution in the
XML file?
2. What options are there for combining XML and java config in such a way
that when I call Caching.getCachingProvider(...).getCacheManager(...), I
get a cache that is the result of both XML and java config? (We are also
evaluating Hazelcast and were able to get things working there over JCache
using this approach.)

Re: How to avoid the event lost in the continuous query

[Vladislav Pyatkov]

Hi,

Local listener need to present on side, where the CC will be invoked, and
remote listener need to be on all server nodes.

Re: Ignite zeppelin jdbc connection

[vdpyatkov]

Hi,

As I know you can configure CacheJdbcPojoStore in order to pairs of various
object save to different tables. But in the case types of key must be
different.

All nodes of cluster need to have value classes on classpath or to configure


  

About loading data from persistent store you can look the article[1]

Re: Hive on Ignited- Yarn

[Vladimir Ozerov]

Hi,

First of all we need to ensure that Ignite is really used in your case.
Please advise which Hadoop deployment you use and where mapred-site.xml and
core-site.xml files you mentioned are located?

Vladimir.

Re: Is ignite installation required on all nodes of hadoop cluster

[Vladimir Ozerov]

Hi,

Could you please provide more information on your use case? 

By default we recommend to have a single Ignite node started on every HDFS
data node so that we can take advantage of data locality and minimize
network traffic. But this is not strict requirement and final cluster
deployment may vary depending on the use case technology stack. So the more
details we have about your use case, the better solution we can advise.

Vladimir.

Re: How to avoid the event lost in the continuous query

[ght230]

How to deployment ContinuousQuery?

Does remoteFilter deploy on Server side and localListener deploy on Client
side?
Or both remoteFilter and localListener deploy on Client side?

Can you show me a detailed example?
