Hi
I have a question when use flink sql 1.11.0
Error:
Exception in thread "main"
org.apache.flink.table.api.NoMatchingTableFactoryException: Could not find a
suitable table factory for 'org.apache.flink.table.delegation.ExecutorFactory'
in
the classpath.
Reason: No factory implements
'org.apache.flink.table.delegation.ExecutorFactory'.
The following properties are requested:
class-name=org.apache.flink.table.planner.delegation.BlinkExecutorFactory
streaming-mode=true
The following factories have been considered:
org.apache.flink.table.module.CoreModuleFactory

My code is:
val settings =
EnvironmentSettings.newInstance().useBlinkPlanner().inStreamingMode().build()
val tableEnv = TableEnvironment.create(settings)
val mapedStream: DataStream[util.Map[String, Any]] =
environment.readTextFile("/Users/weifeng/IdeaProjects/flinksqldemo/src/main/resources/demo.txt",
"utf-8")
.map(x => {
val splits = x.split(",", -1)
var map1: util.Map[String, Any] = new util.LinkedHashMap[String, Any]()
map1.put("mobile_id", splits(0))
map1.put("name", splits(1))
map1
})
val mapedStream1: DataStream[util.Map[String, Any]] =
environment.readTextFile("/Users/weifeng/IdeaProjects/flinksqldemo/src/main/resources/demo.txt",

.map(x => {
val splits = x.split(",", -1)
var map1: util.Map[String, Any] = new util.LinkedHashMap[String, Any]()
map1.put("mobile_id", splits(0))
map1.put("name", splits(1))
map1
})
val name = "mypg"
val defaultDatabase = "bdhtest"
val username = "bdh"
val password = "flRfRO9Lovgc"
val baseUrl = "jdbc:postgresql://10.218.1.190:8433/bdhtest”
val catalog = new JdbcCatalog(name, defaultDatabase, username, password,
baseUrl)
tableEnv.registerCatalog("mypg", catalog)
tableEnv.useCatalog("mypg")
tableEnv.execute("JoinDemo04”)
Thank You

Caizhi Weng created FLINK-18821:
-----------------------------------
Summary: Netty client retry mechanism may cause
PartitionRequestClientFactory#createPartitionRequestClient to wait infinitely
Key: FLINK-18821
URL: https://issues.apache.org/jira/browse/FLINK-18821
Project: Flink
Issue Type: Bug
Components: Runtime / Network
Affects Versions: 1.11.0
Reporter: Caizhi Weng
When running TPCDS 10T benchmark on Flink I found some of the task slots stuck.
After some investigation there seems to be a bug in
{{PartitionRequestClientFactory}}.
When a task tries to require a partition of data from its upstream task but
fails, {{PartitionRequestClientFactory#connect}} will throw
{{RemoteTransportException}} and
{{PartitionRequestClientFactory#connectWithRetries}} will throw
{{CompletionException}}. However this exception is not caught by
{{PartitionRequestClientFactory#connect}} and it will eventually fail the task.
But {{PartitionRequestClientFactory}} lives in a task manager not in a task. In
{{PartitionRequestClientFactory}} a {{ConcurrentHashMap}} named {{clients}} is
maintained for reusing {{NettyPartitionRequestClient}}. When the above
exception happens, {{clients}} is not cleaned up; When the next call to
{{PartitionRequestClientFactory#connect}} with the same connection id comes, it
will use the invalid {{CompletableFuture}} in {{clients}} and this future will
never complete, causing the task to stuck forever.
