No Dialect mapping for JDBC type: -9 (source from oracle 11)

[0xhanh]

I pull data from oracle11g, ~ source oracle; below my flume-ng config:

agentTest.channels = channelTest
agentTest.sources = sourceTest
agentTest.sinks = sinkTest

###########sql source#################

# For each Test of the sources, the type is defined

agentTest.sources.sourceTest.type = org.keedio.flume.source.SQLSource
#agentTest.sources.sourceTest.type = org.keedio.flume.source.SQLServerCustomDialect
agentTest.sources.sourceTest.hibernate.connection.url = jdbc:oracle:thin:@�:1521:orcl

# Hibernate Database connection properties

agentTest.sources.sourceTest.hibernate.connection.user = ...
agentTest.sources.sourceTest.hibernate.connection.password = ...
agentTest.sources.sourceTest.hibernate.connection.autocommit = true
agentTest.sources.sourceTest.hibernate.dialect = org.hibernate.dialect.Oracle10gDialect
agentTest.sources.sourceTest.hibernate.connection.driver_class = oracle.jdbc.driver.OracleDriver
agentTest.sources.sourceTest.run.query.delay=10000
agentTest.sources.sourceTest.enclose.by.quotes = false

agentTest.sources.sourceTest.status.file.path = /usr/local/flume
agentTest.sources.sourceTest.status.file.name = agentTest.sqlSource.status

# Custom query
agentTest.sources.sourceTest.start.from = 0
agentTest.sources.sourceTest.custom.query = my sql select

agentTest.sources.sourceTest.batch.size = 1000
agentTest.sources.sourceTest.max.rows = 1000
agentTest.sources.sourceTest.hibernate.connection.provider_class = org.hibernate.connection.C3P0ConnectionProvider
agentTest.sources.sourceTest.hibernate.c3p0.min_size=1
agentTest.sources.sourceTest.hibernate.c3p0.max_size=10
...
