OSHDB2Ignite errors?

[SlowMo24]

Using a default ignite-config.xml I get following StackTrace:

org.apache.ignite.IgniteException: Cache doesn't exist: grid_node
    at org.apache.ignite.internal.util.IgniteUtils.convertException (IgniteUtils.java:990)
    at org.apache.ignite.internal.cluster.IgniteClusterImpl.changeWalMode (IgniteClusterImpl.java:550)

but changing the order of https://github.com/GIScience/oshdb/blob/master/oshdb-tool/etl/src/main/java/org/heigit/bigspatialdata/oshdb/tool/importer/util/OSHDB2Ignite.java#L79 and https://github.com/GIScience/oshdb/blob/master/oshdb-tool/etl/src/main/java/org/heigit/bigspatialdata/oshdb/tool/importer/util/OSHDB2Ignite.java#L81 does not help because in dafault-config, persistance is disabled. So I guess WAL-Mode should be checked before disabeling it? I just don't know how to :-(

@SlowMo24 I'm not sure what you are trying, but the default-ignite.xml is not suitable for our setup.
You need to enable the persistent store and also peerclassloading in your ignite-conf in order to use the OSHDB2Ignite tool.

I created a patch #53 which reorganize cache creation and wal disable, and also makes sure that wal will be enabled after an import.

But I can set up my own little pseudo-cluster: https://gitlab.gistools.geog.uni-heidelberg.de/giscience/big-data/ohsome/oshdb-benchmarks/blob/ignitebackend/src/main/java/org/heigit/bigspatialdata/oshdb/benchmark/Runner.java#L104 and it works (if not for the WAL thing)

[rtroilo]

Sure, but if you shutdown your cluster, then your data is lost and you need to reimport it again if you want to use it.
We disable WAL btw to speed up bulk-loading, but need to enable it after to import, so that the data get persist.
