>                 Key: CASSANDRA-13675
>                 URL: https://issues.apache.org/jira/browse/CASSANDRA-13675
>             Project: Cassandra
>          Issue Type: Bug
>          Components: Local/Compaction
>            Reporter: Hao Zhong
>            Assignee: Ekaterina Dimitrova
>            Priority: Normal
>             Fix For: 4.x

> The SizeTieredCompactionStrategyOptions_validateOptions method has the 
> following code:
> {code}
>  public static Map<String, String> validateOptions(Map<String, String> 
> options, Map<String, String> uncheckedOptions) throws ConfigurationException
>     {
>         String optionValue = options.get(MIN_SSTABLE_SIZE_KEY);
>         try
>         {
>             long minSSTableSize = optionValue == null ? 
> DEFAULT_MIN_SSTABLE_SIZE : Long.parseLong(optionValue);
>             if (minSSTableSize < 0)
>             {
>                 throw new ConfigurationException(String.format("%s must be 
> non negative: %d", MIN_SSTABLE_SIZE_KEY, minSSTableSize));
>             }
>         }
>         catch (NumberFormatException e)
>         {
>             throw new ConfigurationException(String.format("%s is not a 
> parsable int (base10) for %s", optionValue, MIN_SSTABLE_SIZE_KEY), e);
>         }
>         ...
>     }
> {code}
> Here, the optionValue can be too long and cause overflow. CASSANDRA-8406 
> fixed a similar bug. The buggy code is:
> {code}
> public static Map<String, String> validateOptions(Map<String, String> 
> options, Map<String, String> uncheckedOptions) throws  ConfigurationException
>     {
>         String optionValue = options.get(TIMESTAMP_RESOLUTION_KEY);
>         try
>         {
>             if (optionValue != null)
>                 TimeUnit.valueOf(optionValue);
>         }
>         catch (IllegalArgumentException e)
>         {
>             throw new 
> ConfigurationException(String.format("timestamp_resolution %s is not valid", 
> optionValue));
>         }
>         optionValue = options.get(MAX_SSTABLE_AGE_KEY);
>         try
>         {
>             long maxSStableAge = optionValue == null ? 
> DEFAULT_MAX_SSTABLE_AGE_DAYS : Long.parseLong(optionValue);
>             if (maxSStableAge < 0)
>             {
>                 throw new ConfigurationException(String.format("%s must be 
> non-negative: %d", MAX_SSTABLE_AGE_KEY, maxSStableAge));
>             }

>         }

>  public static Map<String, String> validateOptions(Map<String, String> 
> options, Map<String, String> uncheckedOptions) throws  ConfigurationException
>     {
