消息：RSA premaster祕密錯誤。 ERRORCODE = -4499，SQLSTATE = 08001

我試圖從Bluemix Spark上的iPython筆記本作爲服務連接BigSQL Cloud上的BigSQL羣集。消息：RSA premaster祕密錯誤。 ERRORCODE = -4499，SQLSTATE = 08001

我的筆記本電腦看起來是這樣的：

import os 
cwd = os.getcwd() 

with open('certificate', 'w') as f: 
    f.write('''-----BEGIN CERTIFICATE----- 
XXXXXXXXXXXXXXX 
-----END CERTIFICATE-----''') 

!rm truststore.jks 
!keytool -import -trustcacerts -alias biginsights -file certificate -keystore truststore.jks -storepass mypassword -noprompt 

host = 'ehaasp-xxxxx-master-2.bi.services.bluemix.net' 
user = 'biadmin' 
pwd = 'xxxxxxx' 
url = 'jdbc:db2://{0}:51000/bigsql:user={1};password={2};sslConnection=true;sslTrustStoreLocation={3}/truststore.jks;Password=mypassword;'.format(host, user, pwd, cwd) 

df = sqlContext.read.format('jdbc').options(url=url, 
     driver='com.ibm.db2.jcc.DB2Driver', dbtable='GOSALESDW.SLS_SALES_FACT').load()

我收到的例外是：

Py4JJavaError: An error occurred while calling o111.load.

我在嘗試使用Hive 2.0 jdbc連接時，一個類似的錯誤。

根據該[答案]（https://developer.ibm.com/answers/ questions/206325/how-to-fix-this-ssl-error-javaxnetsslsslkeyexcepti.html），似乎需要在spark服務上安裝無限制的管轄權策略文件。 –

現在已經修復。

我發現根據您找到的link的說明，需要在java目錄下的spark服務上安裝無限管轄權策略文件。在上bluemix用戶火花服務租戶不同意創建/瀏覽java目錄。

n [4]: 
!echo $JAVA_HOME 
/usr/local/src/spark160master/ibm-java-x86_64-80 
In [5]: 
!ls $JAVA_HOME/Security/ 
ls: cannot access /usr/local/src/spark160master/ibm-java-x86_64-80/Security/: No such file or directory 
In [6]: 
!touch $JAVA_HOME/Security/policydummy.txt 
touch: cannot touch '/usr/local/src/spark160master/ibm-java-x86_64-80/Security/policydummy.txt': No such file or directory

這已經注意到作爲一項要求，並作進一步調查將進行審查（鎖定）。

謝謝， Charles。
